Expand and simplify 2 (3m+4) + 3 (m-5)

So we distribute the 2 to the 3m and the + 4 so

2*3m=6m

2*4=8

6m+8

we then distribute the 3 to the m and the - 5

3*m=3m

3*-5=-15 ((+) times (+) or (-) times (-) = (+), (-) times (+) or (+) times (-) = (-))

3m-15

add 6m+8 and 3m-15

6m+8+3m-15

add like terms (m terms + m terms and number + numbers)

6+3=9 so

3m+6m=9m

9m-7
