Answer:
When combining like terms, such as 2x and 3x, we add their coefficients. For example, 2x + 3x = (2+3)x = 5x.
Step-by-step explanation:
example: 1x+2x+5y+3y
if you combine like terms you would be combining anything with a x to other x's and anything with a y to other y's.. etc..
the example combined would be: 3x+8y
