Question

Combine Like Terms -8w + 16x + 20w – 40x

Answer 1

12w - 24x

Explanation:

• Start by grouping terms that are alike. You can identify such terms by looking at the variables. Anything associated with x is considered a like term to another number associated with x.

`-8w+16x+20w-40x\\-8w+20w+16x-40x`

• Add both like elements for each side.

`-8w+20w=12w\\12w+16x-40x\\16x-40x=-24x\\\bold{=12w-24x}`

Hope this helps!
