Question

Solve For x -7=x-4

Answer 1

-7=x-4
-7+4=x-4+4
x=-3
-7=-3-4
-7=-7

Answer 2

Easy

First you need to get the X by its self so do the opposite of what (-4) is doing and add it to both sides

-7 + 4 = -4 + 4

So the (-4 + 4) cancels out and now it’s jus (-7 + 4) now jus solve and you get X

-7 + 4 = -3

So (-3) = X
