Question

the pair of equation 3x=7y+4and 14y=6-8 represents two line which are​

Answer 1

Answer:

3x=7y+4.

14y=6-8

3x-7y=4. .....eq1st

0+14y=-2. ......eq2nd

now multiply eq 1st by 2

(3x-7y=4)2

6x-14y=8 .....eq3rd

now subtract eq 3rd by 2nd

6x-14y=8

0+14y=-2

6x. =6

x. =6/6

x=1. .....eq 4th

now put eq 4th in 1st

3x-7y=4

3(1)-7y=4

3-7y=4

-7y=4-3

-7y=1

y=-1/7
