The equation -3y + 5 = 26 involves two steps. The variable is multiplied by - 3. Then 5 is added. To solve the equation, work backward. First undo the addition by subtracting 5 from each side. Then undo the multiplication by dividing each side by - 3.

- 3y +5 = 26

-3y + 5 - 5 = 26 - 5

-3y/-3 = 21/3

y = -7
