Question

2x+3y=5 & 3x+2y=-1 solve elimination method​

Answer 1

Answer:

the value of y in eg. (i) we get 2x - (3) × (-1) = 5 2x + 3 = 5 ⇒ 2x = 5 - 3 ⇒ 2x = 2 ⇒ x = 1 ∴ x = 1, y = 1

Answer 2

Step-by-step explanation:

2x + 3y = 5. multiplying by 2

=. 4x + 6y = 10

3x + 2y = -1. multiplying by 3

=. 9x + 6y = -3

4x + 6y = 10

9x + 6y = -3

- -. +

__________

-5x =13

x=13/-5

putting value of x

2x + 3y=5

-2×13/5 +3y=5

3y= 5+26/5

3y= 51/5

y= 51/15

y= 17/5
