Answer:
x = 2 or just 2
Step-by-step explanation:
x - 7 + x - 3
x + x = 2x
-7 + (-3) = -10
2x - 10
--------------------
x + x + 12
x + x = 2x
you dont change 12, you keep it the same.
--------------------------------------------------------------
2x - 10 + 2x + 12
2x + 2x = 4x
-10 + 12 = 2
12 is greater so it is positive.
-----------------------------------------
2 + 4x
you have to get rid of the 4 so divide on both sides of the equation.
4x/4 = x
when you divide a number by the same number, it cancels itself out so then
4x is just left with x.
4/2 = 2
so [x = 2]
