Question

Solve this system of simultaneous equations:
3x+4y=19,2x- y=9​

Answer 1

Answer:

x = 5

y = 1

Step-by-step explanation:

3x + 4y =19 ...... (1)

2x - y =9.......(2)

multiplying  equation2 by 4 , we get

4(2x - y )= 36

8x - 4y = 36.......(3)

adding eq. 1 and 3 , we get

11x=55

hence , x = 5

substituting value of x in eq 2 we get,

10 - y = 9

hence, y = 1
