Question

solve : 2x+3y=5 and 5x-3y=2​

Answer 1

Step-by-step explanation:

1. 2x+3y=5 , 2x+3y-5=0
2. 5x-3y=2 , 5x-3y-2=0

equation 1+2

2x+3y-5+5x-3y-2=0

7x =7

x=1

2x+3y=5

2×1+3y=5

3y=3

y=1

Answer 2

Answer:

x=1,y=1

Step-by-step explanation:

2x+3y=5 ------ eq 1

5x-3y=2 -------eq 2

Multiply eq 1 by 5 , eq 2 by 2 and subtract

10x+15y=25

10x-6y=4

y=1

Put the value of y in eq 1

2x+3y=5

2x+3(1)=5

2x+3=5

2x=5-3

x=2/2

x=1
