Is x 1, y 3 a system of binary linear equations Please explain why. Thank you!

In a system of equations, as long as there are two unknowns, and the times of the unknowns are one, it is a binary system of equations!

x and y are both unknowns, the number is one, and the number is binary and unequal to one attempt.

Binary refers to 2 unknowns, and once refers to the number of unknowns, which satisfies the condition of a system of binary equations.

Two binary linear equations with the same unknowns are combined to form a system of binary linear equations. This statement is true, but it is not true if it is reversed.

This sentence can only explain that two binary equations with the same unknowns are combined to form a system of binary equations, and this system of binary equations is only one of all types of binary equations, and it cannot represent all binary systems of equations.

An equation that contains two unknowns, and the term containing unknowns is 1 in order is called a binary linear equation.

Two linear equations that are combined together and contain two unknowns are called binary linear equations.

A set of equations consisting of several equations is called a system of equations. If there are two unknowns in the equation, and the number of terms containing the unknowns is one time, then such a system of equations is called a binary linear equation.

These are the definitions of a system of binary linear equations.

x=1,y=3 is the combination of two equations, and then this system of equations contains a total of two unknowns, and the order of each unknown is 1, according to all the above definitions, it is indeed a binary system of equations.

y=1-x.(1) formula.

x-2y=4 .(2) formula.

Substitute Eq. (1) into Eq. (2).

i.e. x-2*(1-x)=4

Get x=2 and substitute x=2 into equation (1).

Get y=-1, so x=2

y=-1

Untie. Substitute Lu Lu x+y=3 into 1 2(x+y)-3y=51 2 3-3y=5

3y=3/2-5

3y=-7/2

y=-7/6

x=25/6

I hope you can be helpful.

is the simplest system of binary linear equations.

Yes

The system of binary linear equations satisfies three conditions:

There are two unknowns.

Two or more equations.

The highest power of an unknown number is 1

We'll be happy to answer for you.

Special mention: binary systems of linear equationsUntie. It is also a system of binary linear equations.

An equation that contains two unknowns and the number of unknowns is once is a binary equation.

This is not binary because the number of ys is -1

Although there are two unknowns, x is on the denominator, so this equation is a fractional equation, while a binary linear equation is an integral equation.

x+3 y=1 can be converted to y=3 (1-x).

Binary Linear Equation: If an equation contains two unknowns, and the exponent of the unknown is 1, then the integer equation is called a binary linear equation with infinite solutions. The general form of a binary linear equation: ax+by+c=0 (a, b is not 0).

The equation you are talking about, where the unknown number y is in the denominator, is obviously a fractional equation, and the binary linear equation is an integral equation, so x+3 y=1 is not a binary linear equation. Now I get it, FYI.

Simplifying 4(x-y-1)=3(1-y) gives 4x-y=7 and then simplifying -2 x 2+ y 3=2 gives -3x+6=9 combined x=13 y=45 also simplification2(x-y) 3 - x-y 4=-1 gives 10x-10y=24 simplification 6(x+y)-4(2x-y)=16 gives -2x+10y=16 adds the equation to get x=5 y=
