Jon, Anne, Tom, Jonah --

• Math -

7(x-2)+3(x+2)=5(x-6)

7*x-7*2+3*x+3*2=5*x-5*6

7x-14+3x+6=5x-30

7x+3x-5x= -30+14-6

5x= -22 Divide with 5

x= -22/5

I got a different answer, Anonymous.

• Math -

7(x-2)+3(x+2)=5(x-6)
7x-14+3x+6=5x-30 -distribute
10x-14+6=5x-30 -combine like terms
10x-8=5x-30 -get x's on 1 side
5x-8=-30
5x=-22 -isolate the x

x=-22/5
