First, we have to distribute the 4 into the parentheses
y + 4(2y + 3) = 15
y + 8y + 12 = 15
now we can combine like terms and solve for y
9y + 12 = 15
9y = 3
y = 3/9
y = 1/3
hope this helped
Y+4(2y+3)=15
y+8y+12=15
(Simplfy)
9y+12=15
(Subtract 12 from 15)
9y=3
(Divide 9 from both side - 9y/9=3/9)
y=1/3
Answer : 1/3 or 0.3 repeating
