Hi,
Work:
Equation;

First add up numbers and distribute 9 over parenthesis.

Second: collect like terms.

Move variable 59p to left side and change its sign.

Then move constant 123 to right side and change its sign.

Calculate the difference.

Divide both sides of equation by 59.

Hope this helps.
