Question

How can you generate x + 3y + 5 from the expression x + y + 4 + 2y + 1?

Answer 1

by combining like terms.

Explanation:

so you look at what you are given and you see that you have 1x and no other x's. you see that you are given 1y and 2 more y's therefore having 3y's since theyre both positive so you add them. you then see that you have a 4 and a 1 left over, which add to make 5. hope this helped!!!
