<h3>Solution:</h3>

$\frac{4}{5} - ( - \frac{1}{3}) \\ = \frac{4}{5} + \frac{1}{3} \\ = \frac{12 + 5}{15} \\ = \frac{17}{15} \\ = 1 \frac{2}{15}$

Steps:
1. Multiply the first line by 3 and the second by 2
3(3x + 2y= 4)
2(8x -3y=-6)
2. New lines are
9x + 6y= 12
16x + -6y=-12
3. Now add/subtract them
25x + 0= 0
25x=0
4. Divide by 25
X=0

5. To find y, substitute the 0 in the x in one of the equations
9x + 6y= 12
9(0) + 6y= 12
6y= 12
6. Divide by 6, your Y=2
7. X=0, Y=2
