-4x + 16 = 8
Please help me solve in algebric expression
-4x + 16 = 8
Subtract 16 from each side of the equation.
-4x + 16 - 16 = 8 - 16
Combine like terms:
16 - 16 = 0
8 - 16 = -8
-4x = -8
Divide each side by -4
-4x/-4 = -8/-4
x = 2

Check:
-4x + 16 = 8
-4(2) + 16 = 8
-4(2) = -8
-8 + 16 = 8
8 = 8

Therefore:
x = 2
