Answer:
(x,y)=(-2,3)
Step-by-step explanation:
6x+5y=3
x=-(13/2)+(3/2)y
6(- 13/2+3/2y) +5y=3
y=3
x=13/2+3/2x3
x=2
Step-by-step explanation:
let 6x+5y=3 be equation 1
and 2x-3y=-13 be equation 2
Multiply equation 2 by 3
(2x-3y)*3=(-13)*3
6x-9y=-39
Now Solving eq 1 and 2 simultaneously
6x+5y=3
6x-9y=-39
- + =+
_________
0+14y=42
y=42/14
y=3
Put y=3 in eq 1 to find x
6x+5y=3
6x+5(3)=3
6x+15=3
6x=3-15
6x=-12
x=-12/6
x=-2
Therefore y=3
x=-2
