Question

solve for (x-y) by elemination method 3x+2y=4 & 2x+3y=7​

Answer 1

3x+2y = 4....... ×3

2x+3y = 7.......× 2

we get,

9x+6y=12.......(1)

4x+6y=14.......(2)

Solving (1) and (2) we get,-

5x = -2

x= -2/5

substitute the value of x in one of the two equation and find the value of y.

Answer 2

Step-by-step explanation:

we have

3x+2y=4. ----------(1)

2x+3y=7. ----------(2)

multiply equation (1) by 2

multiply equation (2) by 3

we get ,

6x+4y=8. -----------(3)

6x+9y=21 ----------(4)

subtracting equation (3) from (4)

we get

6x+4y=8

-

6x+9y=21

0x+(-5y)=(-13)

y=13/5

putting the value in the equation (1)

3x+3(13/5)=4

x=-13/15
