Question

3x+2y=4 ....(1)
2x+5y=10....(2)

​

Answer 1

Answer:

Multiplying equation 1 by 2 . so ( 6x+4y=8)

Multiplying equation 2 by 3. so (6x+15y=30)

subtracting equation 1 and 2

we get value of y=2 and value of X= -2

Answer 2

Answer:

by elemanation mathod

Explanation:

3x+2y=4 - eqn 1st

2x+5y =10 -eqn 2nd

multiply eqn 1st by 2 &

multiply eqn 2nd by 3

then

2/3x+2/2y =2/4

6x+4y =8 eqn 3rd

3/2x+3/5y=3/10

6x+15y=30 - eqn 4th

substract eqn 4th from 3rd

6x+15y=30

-6x+4y=8

6x is cancel 11y =38

y=38/11

y=3.45

put y =3.45 in eqn 1st

3x+2y=4 -eqn 1st

3x+2/3.45=4

3x+6.9=4

3x=4-6.9

3x=2.9

x=2.9/3

x=0.9666666667
