Question

thanks for the help

Answer 1

Do your own homework

Answer 2

Since you can't have two equals, you might mean 3(x+10) + 4(x+20) or 3(x+10) - 4(x+20)

I'll do both ways.

--------

Using addition:

Distribute

3(x+10) = 3x+30

4(x+20) = 4x+80

Rewrite

3x+30 + 4x+80 + 5x =  185 - 3x

Simplify

12x +110 = 185 - 3x

Simplify

15x = 75

Divide by 15

x=5

---------------

Using subtraction:

3x+30 - 4x+80 + 5x = 185 - 3x

4x + 110 = 185 - 3x

7x = 75

x = 75/7

Since that answer looks a bit odd, I think you meant the addition.

Hope that helped :)
