1 + 4x = -5 + 7x

  -4x          - 4x

 1       = -5 + 3x

+5        +5        

6        = 3x

[tex]\frac{6}{3} = \frac{3x}{3}[/tex]

2 = x

Answer: x = 2

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 = [tex]\frac{- 6}{- 3}[/tex] = 2
