Question

2x - 3y = 9; 2x + y = 13​

Answer 1

Step-by-step explanation:

2x-3y=9

-x, -y=9

x, y=-9

2x+y=13

3x,3y =13

x, y=13/3

Answer 2

Step-by-step explanation:

2x-3y=9--------(1)

2x+y=13---------(2)

subtracting equation (2) from (1) we get

2x-3y=9

2x+y=13

(-) (-) (-)

--------------

-4y= -4

=>y = -4/-4=1

putting the value of y in equation (1) we get

2x-3y=9

=>2x-3×1=9

=>2x-3=9

=>2x=9+3

=>2x=12

=>x=12/2

=>x=6

so x=6 y=1
