1. Solve the following for x.
3(x+(4))= 2x6+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 IP/Pt=r.
The second answer is I1P/t=r.
Are either of these answers correct?

1. Solve the following for x.
3(x+(4))= 2x6+5x
remove innner parentheses.
3(x4)=2x6+5x
remove next set of parentheses.
3x+4=2x6+5x
combine terms on left and right,
7x=7x6
move numbers to right and xs to left.
x7x=67
combine terms.
8x=13
Multiply through by 1
8x = 13
x=13/8
I figured that the answer is no solution. Is this correct?

2. Solve for r. I=P(1+rt)
The first answer is
IP/Pt=r.This one is correct.
The second answer is I1P/t=r.
