Question

What is equivalent to 7(3x-2)+4(x+5)

Answer 1

7(3x-2)+4(x+5)

Distribute and you get

21x - 2 + 4x + 20

Add like terms

25x + 18

Answer 2

Distribute 7 to 3x and -2, and 4 to x and 5

7(3x - 2) = 21x - 14

4(x + 5) = 4x + 20

Combine like terms

21x + 4x = 25x

-14 + 20 = 6

25x + 6 is your answer

hope this helps
