Question

Simplify:
8(v+w) - 7(v+2w)

Answer 1

The answer is v-6w....

Answer 2

first you need to distribute. when you do this you get (8v+8w)-(7v+14w) then you get like terms together, but don't forget that everything in (7v+14w) is negative. when you group like terms together you get (8v-7v)+(8w-14w) simplify and you get v-6w
