Question

2x-y=-3 and 3x-7y=-10 by substituting method ​

Answer 1

Answer:

x = -1, y = 1

Step-by-step explanation:

2x-y =  -3

2x + 3 = y .................................................................(1)

3x-7y= -10

replacing y

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

3x - 14x - 21 = -10

-11x = 11

x = -1

replacing x=-1 in (1)

2*(-1) + 3 = y

y = 1
