Explain in words how you would get the answer to this equation 9x-7=-7=0 explain in words how you would get the answer to this equation 9x-7=-7=0 pls me

See below

Step-by-step explanation:

9x-7=0

We want to isolate the variable, or in other words, get x alone.

The first step is to add 7 to each side to get the constant on one side and the variable on the other

9x-7+7 = 0+7

9x =7

The since we are multiplying x by 9, we need to do the opposite to isolate it.  We will divide by 9.  What we do to one side, we do to the other.  Divide both sides by 9

9x/9 = 7/9

x =9

We have successfully isolated the variable and solved for x.

5+2x=a
