445-x+x=2500+x

445=2500+x

445-2500=2500+x-2500

2055=x

x=-2055

2. Solve the equation according to the relationship between addition, subtraction, multiplication and division.

5-x+440=2500

Solution: 445-x=2500

x=445-2500

x=-2055

Extended information: 1. Solve equations according to the basic properties of equations;

The nature of the equation: the same number is added, subtracted, multiplied, and divided by both sides of the equation at the same time (the divisor is not 0), and the equation still holds.

2. Solve the equation according to the relationship between addition, subtraction, multiplication and division.

1.Equations are solved according to the relationship between the parts of addition.

In other words, an unknown is an addition in the addition equation, and we can find the value of the unknown based on "one addition and another addition".

2.Solve the equation according to the relationship between the parts of subtraction.

In other words, unknowns may be subtracted or subtracted in the subtraction equation. When the unknown is the subtracted number, we can find the value of the unknown number based on the "subtracted subtraction difference".

When the unknown is a minus, we can find the value of the unknown based on the "subtraction subtraction difference".

3.Solve equations according to the relationship between the parts of multiplication.

In other words, an unknown is a multiplier in the multiplication equation, and we can find the value of the unknown number based on "one multiplier product another multiplier".

4.Equations are solved according to the relationship between the parts of the division.

In other words, an unknown number may be the dividend, or it may be the divisor in the division equation. When the unknown is the dividend, we can find the value of the unknown based on the "Dividend Quotient".

When the unknown is the divisor, we can find the value of the unknown based on the "divisor dividend quotient".

Solve the equation hungry Hu.

3200 = 450 + 5 x + x 6 x = 3200 - 450 x = 2750 6 x = 458 and vertical limb ridge 1 residual infiltration 3

This is a one-dimensional equation.

Therefore, according to the requirements of the question, the specific solution process is:

x=450÷5=90.

Therefore, in the process of mathematics calculation, it is very important to accurately grasp the calculation methods and rules, usually learn more with the teacher, learn the knowledge solidly, and pay attention to the efficient learning method when learning and communicating with the teacher.

1.Listen when you talk.

Listening is also a point to pay attention to in communication, when talking to others, we should take into account the feelings of others, and listen to the other party's expression, so that we can better communicate in language, otherwise communication will not achieve the effect at all, and it is easy to misunderstand.

Solution: Divide the two keys by 5.

x=90

Hello! Glad for your question!

Solution: 40 5+5x=440

200+5x=440

5x=440－200

5x=240

x=240÷5

x=48 Your and likes are the biggest support for me! Good luck with you! Thank you!

Solution: 5x=440-40 or 5 5x=440-200 5x=240 x=48
