What is 5(y-2)-2=2(y+1)-5? Solve for y and show your work please.

Inessa [10]

Answer:

y = 3

Step-by-step explanation:

Let's start with the left side of the equation.

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

5y-10-2= 2(y+1)-5

Now let's solve the right side

5y-10-2= 2y+2-5

5y-12= 2y-3

-2y -2y

3y-12=-3

+12 +12

3y = 9

3y/3 = 9/3

y = 3

hope this helps!
