Answer:
A=
Step-by-step explanation:
Factorise
Rewrite it
Distribute the 2 to all terms within the parenthesis
2(x + 8) = 2x + 16
2x + 16 = x + 20
Isolate the x. Subtract x from both sides and 16
2x (-x) + 16 (-16) = x (-x) + 20 (-16)
2x - x = 20 - 16
Simplify. Combine like terms.
x = 4
C. 4 is your answer
