Question

find three different solutions of the each of the following questions 2x-y=7


​

Answer 1

Answer:

Given equation 2x−y=7

(i)2x−y=7

If x=2 put the equation we get

2×2−y=7

⇒4−y=7

⇒−y=7−4

⇒y=−3

(2,-3)

(ii)2x−y=7

If x=3 put the equation we get

2×6−y=7

⇒6−y=7

⇒−y=7−6

⇒y=−1

(3,-1)

(i)2x−y=7

If x=4 put the equation we get

2×4−y=7

⇒8−y=7

⇒−y=7−8

⇒y=1

(4,1)
