Question

solve the following pair of linear equation by solving method 2x-3y=19 and 3x-2y=21

Answer 1

2x-3y=19 ----------(1) ×3

3x-2y=21----------(2) ×2

6x-9y=57

6x-4y=42

- + = -

____________

- 5y= -15

cancel this subtract sign then the equation will become

5y=15

y=15

____

5

y=3

2x-3y=19----------(1) ×2

3x-2y=21----------(2)×3

4x-6y=38

9x-6y=63

- - = -

____________

-5x = -25

x= 25

____

5

x= 5

this is the answer hope it helps you sum
