Question

If 4x - 16 = 32, what is 4x?

Answer 1

x=12

Explanation:

Given,

4x-16=32

4x=32+16(We transpose LHS to RHS)

4x=48

x=48/4

x=12

Hence, the answer is 12

Answer 2

Answer: X = -12

Explanation:

-4x-16=32

We move all terms to the left:

-4x-16-(32)=0

We add all the numbers together, and all the variables

-4x-48=0

We move all terms containing x to the left, all other terms to the right

-4x=48

x=48/-4

x=-12
