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

Respuesta :

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

Given equation is:

[tex]4x+12=8[/tex]

Solving it, we get,

[tex]4x=-4[/tex] 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.

[tex]x=\frac{-4}{4}[/tex] This step includes division, to find the value of x

[tex]x=1[/tex]

So, the correct answer is option A. Division
