Question

13(y-4)-3(y-9)-5(y+4)=0

Answer 1

y=9

Explanation:

13(y-4)-3(y-9)-5(y+4)=0

1) Distribute 13 to y and -4:

13y-52

2) Distribute -3 to y and -9:

13y-52-3y+27

3) Distribute -5 to y and 4:

13y-52-3y+27-5y-20=0

4) Combine alike terms:

5y-45=0

5) Add 45 to both sides:

5y=45

6) Divide both sides by 5:

y=9
