The solution to the system of equation is x = 9 /2 and y = - 3 / 2
<h3>
Simultaneous equation</h3>
y = 5 / 3 x + 3
y = 1 / 3 x - 3
Therefore, let subtract equation(i) from equation (ii) to eliminate y
5 / 3 x - 1 / 3 x = 3 + 3
5x - x / 3 = 6
4x / 3 = 6
cross multiply
18 = 4x
x = 18 / 4
x = 9 / 2
Therefore,
y = 1 / 3(9 / 2) - 3
y = 9 / 6 - 3
y = 9 - 18 / 6
y = - 9 / 6
y = - 3 / 2

______
4
u can do the rest
3x - 9x + 7 - 3 = -8
-6x +4 =-8
-6x = -12
Divide that by -6
x = 2
