Question

X+y=5
2x-3y=4
please solve this problem by step by step​

Answer 1

Step-by-step explanation:

x+y=5--------(i)×2

2x-3y=4------(ii)×1

2x+2y=10

2x-3y=4

(-) (+) (-)

5y=6

y=6/5

putting y=6/5 in equation (i) we get,

5x+6=25

x=19/5

Answer 2

x+y=5 (1)

2x-3y=4 (2)

multiplying equation(1) by (2)

2 (x+y)=2×5

2x+2y=10......(3)

subtracting (3)from(2)

2x+2y=10

2x+3y=4

(-) (-) (-)

-5y=-6
