I will like to know how to solve this
Olenka [21]

x = 2

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

1 + 4x = - 5 + 7x ( subtract 7x from both sides )

1 + 4x - 7x = - 5

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

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

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