Question

Substitution 3x-y-4=0,4x+y-17=0​

Answer 1

Answer:

Step-by-step explanation:

6xy-7=0. 1

4xy-6=0. 2

x=+7/6y. 3

y=6/4x. 4

substituting values

x=7/6(6/4x)

x=7/36/4x

x=28x/36

36x=28x

36x-28x=

8x=1/8

then find the value of y by the value of x

Answer 2

Answer:

3x-y=4 first equation

4x+y=17 second equation

adding both equation

7x=21

x=3

put the volue of x in equation first

9-y=4

-y=-5

y=5
