5x+130=8x+151
subtract 5x from each side
5x-5x+130=8x-5x+151
130 = 3x+151
subtract 151 from each side
130-151 =3x
-21 = 3x
divide by 3
-21/3 = 3x/3
-7 =x

Answer:
Step-by-step explanation:
You don't say whether this is compound interest or simple interest.
I will assume it's compounding that interests you.
The appropriate formula is
A = P(1 + r)^t, where r is the interest rate as a decimal fraction, t is the time in years, and P is the original amount. Thus:
A = $1000·(1 + 0.05)^t, or A = $1000·(1.05)^t
