Question

2x-3y=2 and x+2y=8 elimination method
​

Answer 1

Answer:

multiply eq 2 by 2 and subtracting it from 1

2x-3y=2

-2x-4y=-16

-7y=-14

y=2

x=8-4= 4

Answer 2

Answer:

x=4

y= 2

Step-by-step explanation:

multiply eq (i) by 2(2x-3y=2)

Or

eq. (ii) by 3(x+2y=8)

4x -6y =4 eq (i)

6x +6y =24 eq(ii)

________

7x =28

x = 28/7

x = 4

now put x vale in any equation

equation (i)

2x - 3y = 2

2*4 - 3y = 2

8-3y= 2

8-2 = 3y

y = 6/3

y= 2
