Answer:

x=7

Step-by-step explanation:

add 7 to both sides

9x=5x+28

subtract 5x from both sides

4x=28

divide both sides by 4

x=7

Answer:

X=7

Step-by-step explanation:

So first you want x on one side so you so subtract 5x from both sides

Then your equation is 4x-7=21

Because you want x by itself, you add 7 to each side because of additive inverse

The equation is now 4x=28

The last step is to divide 4 from each side and that leaves us with 7

x=7
