Answer:
x = 20
Explanation:
PEMDAS
P = parenthasees
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
this is the order
so first
4x + 8 -2x = 4x - 12
No exponents
no Multiplication
No division
Addition
So for this, we have to subtract the 4x on both sides to get
x + 8 - 2x = -12
then do -8
x - 2x = -20
then
-x = -20
x = 20
