Question

Which expressions are equivalent to x + 2y + x + 2x+2y+x+2x, plus, 2, y, plus, x, plus, 2 ?

Answer 1

8x + 5y + 4

Explanation:

Rather than looking for a definite answer for both x and y, you are only going to combine like terms. Simply add x + x and y + y and any coefficients left such as the 2 2’s left without variables. Once all like terms are combined with another, you are finished!

Hope this helped!
