How to check the fifth grade equation 2 8X X 1 71, it should be detailed 5

Solution: x=

x=check: Bring x= into the equation.

Because the equation holds.

So x=is the solution.

Solution: x=

x=Bring x= into the original form.

then the equation holds. x= is the solution of the original equation.

Solution: x=

x=brings the answer into the original rule.

Because the equation holds.

So x=is the solution.

x can be thought of as 1x merging the same kind of items.

x(x=x=

Move to the front, and the recipe is OK.

Don't rely on others, rely on yourself.

It's tough, you'll know it in the 5th grade. It's much better than me.

(x=18 85, test: when x=18 85, the left side of the equation = right, x=18 85 is the solution of the original equation.)

According to the meaning of the title, Zen can be a void to attack the sail:

15x=18

x=18/15

x=6 cavity hail 5
