Question

SOLVE
S. 'x+4 - 3x = 1+x​

Answer 1

`x =1`

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:

`(-3x)/(-3)  = (-3)/(-3)`

`==> x = 1`
