Question

2x-y+3=0 and 3x-7y+10=0​

Answer 1

Answer:

x = -1, y = 1

Step-by-step explanation:

2x-y+3=0 -------(1)

3x-7y+10=0 ----(2)

(2x-y=-3 )×7

3x-7y=-10

14x-7y=-21

3x-7y=-10

- + +

11x = -11 (-7y+7y gets cancelled)

x = -1

On putting value,we get,

2x-y= -3

(2×-1)-y=-3

-y=-3+2

-y=-1

y=1
