Question

Consider this equation:

-2x - 4 + 5x = 8
Generate a plan to solve for the variable. Describe the
steps that will be used.

Answer 1

-2x - 4 + 5x = 8 3x- 4 = 8 3x=8+4 3x= 12 X=4

Answer 2

−2x−4+5x=8
−2x+−4+5x=8
(−2x+5x)+(−4)=8
(Combine Like Terms)
3x+−4=8
3x−4=8
Step 2: Add 4 to both sides.
3x−4+4=8+4
3x=12
Step 3: Divide both sides by 3.
3x/3=12/3
x=4
