Question

1+ 3x − x = x − 4 + 2x

Answer 1

x=5

Explanation:

1+2x=x-4+2x - Add similar elements (3x-x=2x)

1+2x=x+2x-4 - Group like terms

1+2x=3x-4 - Add similar elements (x+2x=3x)

1+2x-1=3x-4-1 - Subtract 1 from both sides

2x=3x-5 - Simplify

2x-3x=3x-5-3x - Subtract 3x from both sides

-x=-5 - Simplify

-x/-1 = -5/-11 - Divide both sides by -1

x=5 - final answer

Answer 2

Short answer:
x=5

Worked answer:
1+3x-x=x-4+2x
1+2x=3x-4
-x=-5
x=5

I hope this helps!
