x = 2

Collect terms in x on one side of the equation and numeric values on the other

subtract 7x from both sides

1 + 4x - 7x = - 5

1 - 3x = - 5 ( subtract 1 from both sides )

- 3x = - 5 - 1 = - 6 ( divide both sides by - 3 )

x = \frac{- 6}{- 3} = 2

1 + 4x = -5 + 7x

<u>   -4x  </u>    <u>    - 4x </u>

 1       = -5 + 3x

<u>+5     </u>    <u>+5        </u>

6        = 3x

\frac{6}{3} = \frac{3x}{3}

2 = x

Answer: x = 2
