Question

solve 2x-3y=-1,5x+4y=9​

Answer 1

Answer:

Step-by-step explanation:

5x+4y=9

x+2y=3

[multiplying equation no. (2) by 2]

we get,

2x+4y=6

[subtracting equation no. (3) from (1)]

3x=3

x=3/3

x=1

[substituting x=1 in equation no.(2)]

x+2y=3

(1)+2y=3

1+2y=3

2y=3-1

2y=2

y=2/2

y=1

SOLUTION:

x= 1 y = 1
