You can put this solution on YOUR website!
3x - 5(3x - 7) = 2(x + 9) + 45
3x-5(3x)-5(-7)=2(x)+2(9)+45
3x-15x+35=2x+18+45
-12x+35=2x+63
-12x-2x+35=-2x+2x+63
-14x+35=63
-14x+35-35=63-35
-14x=28
-14x/-14=28/-14
highlight%28x=-2%29
Check if x=-2 does the equation equal?
3(-2)-5(3(-2)-7)=2(-2+9)+45
-6-5(-6-7)=2(7)+45
-6-5(-13)=14+45
-6+65=59
59=59 Yes, we're right!!!
Happy Calculating!!!!
