Question

Find the value of variables x and y. 4x+6/y = 19 3x- 4/y = 10​

Answer 1

Step-by-step explanation:

4x+6/y=19----------(1)

3x-4/y=10-----------(2)

(1)×3=12x+18/y=57

(2)×4=12x-16/y=40

(-) (+) (-)

----------------------------

34/y=17

=>17y=34

=>y=2

putting the value of y in equation (1) we can get

4x+6/y=19

=>4x+6/2=19

=>4x+3=19

=>4x=16

=>x=4

Answer 2

Answer:

Given equation are :

Multiply equation (1) by 3 ans (2) by , we get

on subtracting equations (4) from (3) , we get

on putting y = 2 in (1) , we get
