Question

Write an equivalent expression for the following

x + x + x + 2x + x
(x + 2) + (x + 2)
y + y + y + y + 10 + y + 1

Answer 1

1) 6x

2) 2x + 4

3) 5y + 11

Explanation:

For equivalent expressions, you could just add all the variables together.

x + x + x + 2x + x

= 6x

(x + 2) + (x + 2)

= 2x + 4

y + y + y + y + 10 + y + 1

= 5y + 11
