Please show work.

This equation is invalid, the left and right sides are not equal, therefore there is no so

Step-by-step explanation:

Simplifying

5 + 2y = 13 + 2y

Add '-2y' to each side of the equation.

5 + 2y + -2y = 13 + 2y + -2y

Combine like terms: 2y + -2y = 0

5 + 0 = 13 + 2y + -2y

5 = 13 + 2y + -2y

Combine like terms: 2y + -2y = 0

5 = 13 + 0

5 = 13

Solving

5 = 13
