Question

To find the values of x and y for the equations x- 2 y =5 and 2 x+ 3 y =10

Answer 1

Answer:

x - 2y = 5. (1)

2x + 3y = 10. (2)

multiply equation (1) by 2

2x - 4y = 10

subract equation (3) from (2)

2x + 3y = 10

2x - 4y = 10

- y. = 0

y = 0

put value of y in equation (1)

x - 2(0) = 5

x= 5

x= 5

x= 5 & y= 1
