Question

simplify expression

6(3m-7)-2(12y-5)+4(y+6)

Answer 1

6(3m-7)-2(12y-5)+4(y+6)

18m - 42 - 24y + 10 + 4y + 24

18m - 20y - 8

Answer 2

Just use the distributive property to get rid of the parentheses:

6(3m-7)-2(12y-5)+4(y+6)
6(3m)-6(7)-2(12y)-2(-5)+4(y)+4(6)
18m-42-24y+10+4y+24

Now you can use the commutative property to rearrange things:

18m-24y+4y-42+10+24
18m+y(-24+4)-8
18m-20y-8

If that m was really supposed to be a y, then you can fix it, I assume.
