Answer:

Step-by-step explanation:

12(5+2y)=4y-(6-9y)

Distribute

12*5 +12*2y = 4y - 6 +9y

60 +24y = 4y - 6 +9y

Combine like terms

60+24y =13y -6

Subtract 13 y from each side

60 +24y-13y=13y-13y -6

60+11y = -6

Subtract 60 from each side

60+11y-60 =-6 -60

11y = -66

Divide by 11

11y/11 = -66/11

y =-6

Check

12(5+2(-6))=4(-6)-(6-9(-6) )

12 (5-12) = -24 - (6+54)

12(-7) = -24 -60

-84 = -84

True so the solution is correct
