Given the numerical equation: -15y - (-14y) = - 9

Solve for y.

Solution:

Combine first -15y and -14y. Noticed that before -14y there is a negative sign, meaning that the operation will become positive. 

-15y - (-14y) = - 9

 -15y + 14y = -9

-y = -9

Multiply both sides of the equation in order to have a positive y.

y = 9
