Question

3x-2y=12 x-y=-1 vilopan vidhi se hal kijiye

Answer 1

Answer:

3x-2y=12 equation 1

x-y=-1 equation 2

multiplying equation 2 by 2, we get

2x-2y=-2 equation 3

subtracting equation 1 and 2,

3x-2y=12

2x-2y=-2

- + +

x =14

substituting x=14 in equation 2,

x-y=-1

14-y=-1

y=14+1

y=15

therefore x=14 and y=15.
