Answer 3

Not quite @kittywhite here let me take a crack at it...

Answer 4

So you start off with

2x - 5 = 3(2x + 5)

You first want to distribute that 3 into the parenthesis....distribute means multiply into each term...so

what is 3 times 2x?
what is 3 times 5?

This will leave us with

2x - 5 = 6x + 15

what would be do next...?

Answer 5

2x – 5 = 3(2x + 5)
2x - 5 = 6x + 15
2x -5 + 5 = 6x + 15 + 5
2x = 6x + 20
2x - 6x = 6x-6x + 20
-4x = 20
-4x/-4 = 20/-4
x = -5
I think..
