Question

(2x+3x-6) + (x-18+6)=

Answer 1

what are the rules? to solving this problem?

Answer 2

Pretend the parentheses arent there, and combine like terms. Do you know how to do that?

Answer 3

find the common factor?

Answer 4

i mean the lowest common factor

Answer 5

No, combine like terms

Answer 6

2x+x=3x?

Answer 7

2x+3x=5x-6

Answer 8

Combining like terms:
Combine (add or subtract) everything that has the same base/ is the same. for an example, if there is 6x+2, you cannot combine that because 2 does not have an x term with it. However, you can do 3x+7x (=10x) because they both have a variable attached (x).
You can also do a simple 5+1(=6) because they both have the same base

Answer 9

Answer 20

Answer 22

Right, so x=0
