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]
