Answer:

6x + 19 + 3x + -6 + 5x + -15 = 180

19 + -6 + -15 + 6x + 3x + 5x = 180

19 + -6 = 13

13 + -15 + 6x + 3x + 5x = 180

13 + -15 = -2

-2 + 6x + 3x + 5x = 180

6x + 3x = 9x

-2 + 9x + 5x = 180

9x + 5x = 14x

-2 + 14x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 14x = 180 + 2

-2 + 2 = 0

0 + 14x = 180 + 2

14x = 180 + 2

180 + 2 = 182

14x = 182

Divide each side by '14'.

x = 13

6x+19+3x-6+5x-15=180

14x = 180 - 19 + 6 + 15

14x = 182

x = 182 : 14

x = 13

Solution:

<em>Simple Interest = Principal Amount × Rate of Interest/100 × Time</em>

Here, Principal Amount = $6000

Rate of Interest = 6%

Time = 4 years

Simple Interest = 6000 × 6/100 × 4 = <em>$1440</em>
