1. Solve the following for x.
3-(x+(-4))= 2x-6+5x

I figured that the answer is no solution. Is this correct?

I have been working with my friend on this next problem and neither of us know which is correct.
2. Solve for r. I=P(1+rt)
The first answer is I-P/Pt=r.
The second answer is I-1P/t=r.
Are either of these answers correct?

    1. Solve the following for x.
    3-(x+(-4))= 2x-6+5x
    remove innner parentheses.
    3-(x-4)=2x-6+5x
    remove next set of parentheses.
    3-x+4=2x-6+5x
    combine terms on left and right,
    7-x=7x-6
    move numbers to right and xs to left.
    -x-7x=-6-7
    combine terms.
    -8x=-13
    Multiply through by -1
    8x = 13
    x=13/8
