Question

3x+4y=10 और 2x-3y=2​

Answer 1

Answer:

2x - 3y = 2 eq (1)

3x + 4y = 10

3X = 10 - 4y

X = 10 - 4y. eq 2

3

now put the value o FF (X) in eq (1)

2 ( 10 - 4y ) - 3y = 2

3

20 - 8y - 3y = 2

3

20 - 8y - 9y = 2

3

- 17y = 6 - 20

- 17 y = - 14

y = 14/ 17 eq 3

now now put the value of y in equation 2

X = 10 - 4× 14 = - 307.33

3× 17
