Answer:
To simplify the expression, you can start by using the distributive property of multiplication over addition/subtraction and then combine like terms.
1/3(3m+6) - 2(2m+6)
= 1/33m + 1/36 - 22m - 26 (distribute the multiplication)
= m + 2 - 4m - 12 (simplify by multiplying and adding the terms)
= -3m - 10 (combine like terms)
Therefore, 1/3(3m+6)-2(2m+6) simplifies to -3m - 10.
