Add like terms first
-7x - 3x = -10x

so we have -10x + 2 = -8x - 8
-> 2 = 2x - 8 [added 10x to both sides]
-> 10 = 2x [added 8 to both sides]
-> x = 5 [divided both sides by 2

therefore the answer is x = 5

Answer:

<em>Mrs. Adams will earn $3,120 of interest at the end of year 8.</em>

Step-by-step explanation:

<u>Simple Interest</u>

In simple interest, the money earns interest at a fixed rate, assuming no new money is coming in or out of the account.

We can calculate the interests earned by an investment of value A in a period of time t, at an interest rate r with the formula:

$I=A.r.t$

Mrs. Adams deposited an amount of A=$12,000 into an account that earns an annual simple interest rate of r=3.25%. We must find the interest earned in t=8 years. The interest rate is converted to decimal as:

$r=3.25/100=0.0325$
