Question

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

Answer 1

Answer:

no solution

Step-by-step explanation:

$5(y+1)-7=3(y-1)+2y\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\5y+5-7=3y-3+2y\qquad\text{combine like terms}\\\\5y+(5-7)=(3y+2y)-3\\\\5y-2=5y-3\qquad\text{subtract}\ 5y\ \text{from both sides}\\\\-2=-3\qquad\bold{FALSE}$
