Question

3x-7y=-19 y-2x=3 subsitution methodhuuu​

Answer 1

Answer:

the value of x is -2/11

the value of y is 29/11

Answer 2

Answer:

3x-7y=-19. (1)

y-2x=3. (2)

from equation(1)

3x=-19+7y

x=-19+7y/3

putting this value in equation (2)

y-2×-19+7y/3=3

y+38-14y/3=3

3y+38-14y=9

-11y=9-38

-11y=-29

then y=29/11

then putting this value in equation (2)

29/11-2x=3

29-22x=33

-22x=33-29

22x=4

x=11/2

then X=11/2 and y= 29/11
