Question 647230
8(7-y)=-24

56-8y = -24

Now remember whatever you do to one side, you must do to the other.

56 - 8y -56 = -24 - 56
56-56 -8y = -80
0-8y = -80
-8y = -80
-8y/-8 = -80/-8
-8/-8 * y = 10
1* y = 01
y=10


Substitute this value back into the original equation to make sure it is correct.
