PLEASE HELP ME! I REALLY NEED HELP! NO ONE EVER HELPS ME AT HOME!!!! PLEASE!!!

Write an equation that you could solve using these steps:

Add 7 to both sides. Then, divide both sides by 4.

Explain how you know your answer is right.

Answer 1

Remember that the steps you use to solve an equation are the reverse operations of what is happening to the variable.

Answer 2

That means if you need to divide by 4, the variable is being multiplied by 4.
If you need to add 7, that means 7 is being subtracted.

Answer 3

Write an equation using x as the variable.
Multiply x by 4 and subtract 7.
Set it equal to any number you want.

Answer 4

I still dont understand.

Answer 5

Use x as the variable
x

Multiply x by 4:

4x

Subtract 7 from it

4x - 7

Set it equal to any number

4x - 7 = 9

This is an equation that can be solved using the two steps your problem describes.

Answer 6

Applying inverse operations in the opposite order does not affect the result.

Answer 7

you are right
