Answer:
y = 5
Because [2y] is on both sides of the equation, 8y must be equal to [40] so that the equation is true.
Explanation:
Combine like terms to find the value of y.
8y + 2y = 2y + 40
10y = 2y + 40
8y = 40
y = 5
As we can see, we ended with 8y = 40, and 2y is the only term on both sides of the equation.
