Question

Which value of y mAkes the equation below true. 3y+8-7y=11

Answer 1

We have
$3y+8-7y=11$
First, we can combine like terms 3y and -7y to get -4y.
Then, we have$-4y+8=11$ We could then subtract 8 on both sides to get $-4y=3$
Finally,  we isolate y completely by dividing both sides by -4, to get
$y=- \frac{3}{4}$
