Answer:
y=-6
Explanation:
Hi there!
We are given the equation 7y+15=-27 and we want to solve it for y
Our goal is to isolate 1y (also written as just simply y) by itself on one side.
So let's subtract 15 from both sides to remove it from the left side:
7y+15=-27
-15 -15
_____________
7y = -42
Now there are no numbers on the left side, but we aren't done yet. Remember that we want to find 1y, not 7y.
Dividing any number by itself will result in 1 (ex. 3÷3=1). Therefore, we should divide both sides by 7 to find the value of 1y
7y = -42
÷7 ÷7
__________
y = -6
Hope this helps!
