Question

For each equation, choose the statement that describes its solution. if applicable, give the solution.

5(y+1)-7 = 3(y-1)+2y


no solution


y = ?


all real numbers are solutions

Answer 1

This equation has no solution.

Explanation:

Perform the indicated multiplication: 5(y+1)-7 = 3(y-1)+2y

We get 5y + 5 - 7 = 3y - 3 + 2y. Subtracting 5y from both sides yields -2 = -3, which is never true. This equation has no solution.
