Question

2x-y=9 and 3x + 2y =-3 solve by elimination method ​

Answer 1

By using elimination method:

Given, equation,

2x-y=9...1

3x+2y=-3...2

Multiply by 2 in equation....1

4x-2y=18...3

Now, Adding equation 2 and 3

3x+2y+4x-2y=-3+18

7x=15

x=15/7

Putting tha value of x in equation.1

2×15/7-y=9

30/7-y=9

y=30/7×9=10/21
