Just plug them into the equation buddy :)

I = PxRxT
$350 =$700x0.10xT

Dollar signs cancel, yielding 0.5 then divide this by 0.10 and you get a simple 5÷1 or 5 !!!

So it is in terms of years and every other variable cancelled out anyways, so it has to be in years.   SO 5 years :)

Answer:

<u>The solution of this system of equation is ( 3, - 8)</u>

Step-by-step explanation:

1. Let's solve the system of equations:

First equation:

x + 2y = - 13

x = - 13 - 2y

Second equation:

12x + 5y = -4

12 * (- 13 - 2y) + 5y = - 4 (Replacing x with - 13 - 2y)

-156 -24y + 5y = - 4

-24y + 5y = - 4 + 156 (Like terms)

-19y = 152

y = - 152/19

<u>y = -8</u> (Dividing by 19)

Solving x

x + 2y = -13

x + 2 (- 8 ) = - 13

x - 16 = - 13

x = - 13 + 16

<u>x = 3</u>

2. Proving that x = 3 and y = - 8 are correct:

12x + 5y = -4

12 * 3 + 5 * -8 = -4

36 - 40 = - 4

- 4 = - 4

<u>We proved that x = 3 and y = - 8 are correct</u>
