To solve - 9 - 16m = 7, what steps would you use?

Reorder the polynomial

-6m - 9=7

since - 9 doesnt contain a variable move it to the right side of the equation by adding 9 to both sides

-6m=9+7

add 7 and 9 to get 16

divide each term in the equation by - 6

-6m/-6 = - 16/6

reduce

m = - 8/3

-9-16m=7

(+16m) (+16m)

-9=7+16m

(-7) (-7)

-16=16m

(/16) (/16)

-1=m (or m=-1)
