Question

What is the reason for the last step in the argument?

Solve for x:

4x + 12 = 8 (given)

4x=-4(subtraction)

X=-1


A. Division

B. Addition

C. Subtraction

D. Symmetric property

Answer 1

A. Division. -4/4=-1.

Answer 2

Given equation is:

`4x+12=8`

Solving it, we get,

`4x=-4` This is subtraction part. We are grouping the like terms on one side. So, 4x remains on one side and 8-12 will go to the other side.

`x=(-4)/(4)` This step includes division, to find the value of x

`x=1`

So, the correct answer is option A. Division
