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

Answer:
10/6
Step-by-step explanation:
all you have to do is divide x2 or 5 in this case - x2 or -5 with y2 or 3 - y1 or 3 so it would be
(5--5)/(3--3)
and 2 negatives are a positive so it would turn to
5+5/3+3 or 10/6
please rate 5 stars i would really appreciate it
10, because 6(2) is 12 then you divide that by 3 which is four to which you add 6. therefore the answer is 10.
