Question

X + 2x + 12y + 4 Using the expression shown, add like terms and produce an equivalent expression.

Answer 1

3x + 12y + 4

I dont really know how to explain but since there is an X at the and of the 2, you can add X + 2x to get 3x. Since 3x, 12y, and 4 are not alike, this is the simplest form.

Answer 2

Answer: 3x+12y+4

Explanation:

The only like terms are the x+2x so we add them to get the simplfied answer
