Answer:
y=-1
Explanation:
-18=6y+6(1+3y)
1. distribute the parentheses
-18=6y+6+18y
subtract the six from the -18
the six canceling each other out
-24=6y+18y
Add the variables
-24=24y
divide by 24
Y= -1
Answer:-1
I rewrote it so it looks like this:
6y+6(1+3y)=-18
6y+6(1)+6(3y)=-18
6y+6+18y=-18
24y+6=-18
-6 -6
24y=-24
24 24
