Answer:
x = 74/39 , y = 6/13
Step-by-step explanation:
I THINK YOUR QUESTION IS WRONG, STILL THE ANSWER FOR YOUR GIVEN QUESTION IS,
6x - 3y = -10 ----(i)
3x + 5y = 8 ---- (ii)
Multiplying eq-(ii) with 2 (to equate the coefficients of x)
now change the signs and subtract!
6x - 3y = -10
6x + 10y = 16
(-) (-) (-)
you will get 13y = 6
y = 6/13
now substitute y in any one of those equations
I am substituting with eq (ii)
3x + 5y = 8
3x + 5 x (6/13) = 8
3x + 30/13 = 8
3x = 8 - 30/13
3x = 104-30/13 ==> 74/13
therefore, x = 74/13/3
= 74/13 x 1/3
= 74/39
so your x is 74/39 and y is 6/13
