1. In algebra, like terms are terms that have the same variables and powers.

2. What is combining like terms? We call terms "like terms" if they have the same variable part.

3. Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication. CLOSURE: Polynomials will be closed under an operation if the operation produces another polynomial. ... Polynomials are closed under subtraction.

Elimination using addition and subtraction. <br> -4x+4y=-20<br> -2x+4y=-2
goldfiish [28.3K]

I would subtract the 2nd from the first one

so -4x - -2x = -2x

4y - 4y = 0

-20 - -2 = -18


-2x = -18

now I would divide that by -2 to get the value for x

so no we have x = 9


now you just have to substitute that into one of the equations and simplify to get y


-2 X 9 + 4y = -2

-18 + 4y = -2

4y =16

y = 4
