Answer:
y = -5 10/11
Explanation:
12(5+2y)=4y-(5-9y)
Distribute
12*5 +12*2y = 4y - 5 +9y
60 +24y = 4y - 5 +9y
Combine like terms
60+24y =13y -5
Subtract 13 y from each side
60 +24y-13y=13y-13y -5
60+11y = -5
Subtract 60 from each side
60+11y-60 =-5 -60
11y = -65
Divide by 11
11y/11 = -65/11
y =-65/11
Change to a mixed number
11 goes into 65 5 times (5*11=55) with 10 left over
y = -5 10/11
