Question 660097: Please help me solve this. I have done it a million times and keep getting the wrong answer.
2(x+3.5)+4(2x-1)=7x-5(2x+3)
Here is my work
2x+7+8x-4=7x-10x-15
10x-3=-3x-15
13x=-12
x=-12/13
My professor has given us the correct answer of x=-4/9
But I can not figure out how to get to this. Thank you for your help!

2(x+3.5)+4(2x-1)=7x-5(2x+3)

2*x+2*3.5+4*2x-4*1=7x-5*2x-5*3

2x+7+8x-4=7x-10x-15

10x+3=7x-10x-15

10x+3=-3x-15

10x=-3x-15-3

10x+3x=-15-3

13x=-15-3

13x=-18

x = -18/13

So there's a typo somewhere. Double check everything please. Thanks.
