Question

how would i solve this. b+8 - b+4? then b+4 - b ?

Answer 1

Combine like terms. Like terms are terms that have the same variable part.
All the terms with b are like terms. All terms without b are like terms.
b + 8 - b + 4 =
b - b + 8 + 4 =
12

Answer 2

I see. so for b+4 -b i'd do , b-b+4 =4?

Answer 3

correct

Answer 4

For x + y + 6 - x + y +9, you'd do
x - x + y + y + 6 + 9 =
2y + 15
