Question

How many solutions does equation 4x + 3 - 1 = 2(2x + 2) - 2x have explain your reasoning.

Answer 1

one solution

Explanation:

Given

4x + 3 - 1 = 2(2x + 2) - 2x ← distribute parenthesis on right side

4x + 2 = 4x + 4 - 2x

4x + 2 = 2x + 4 ( subtract 2x from both sides )

2x + 2 = 4 ( subtract 2 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Answer 2

Anwser: X=1

4x+3-1=2(2x+2)-2x

4x+2=4x+4-2x

4x+2=2x+4

-2 -2x

2x=2

X=1
