Answer:
[tex]x =1[/tex]
Step-by-step explanation:
x + 4 - 3x = 1 + x
Combine like terms:
x - 3x
==> -2x
4 - 2x = 1 + x
Subtract x to each side:
-2x - x x - x
-3x 0
4 - 3x = 1
Subtract 4 from each side:
4 - 4 1 - 4
0 -3
-3x = -3
Divide -3 from each side:
[tex]\frac{-3x}{-3} = \frac{-3}{-3}[/tex]
[tex]==> x = 1[/tex]
