Answer:
multiply equation 1by -3 and multiply equation 2 by 1
-3×2x+3y×-3=13×-3
-6x+4y=0
-6x-9y=-39
-6x+4y=0
Step-by-step explanation:
-13y=-39
divide both side by -13
-13y/-13=-39/-13
y=3
put answer of y in equation 1
2x+3y=13
2x+3×3=13
2x+9=13
take like terms of the equation
2x=13-9
2x=4
divide both side by 2
2x/2=4\2
x=2
(x,y)=(2,3)
