Four solutions of 2x+y=7 |
|
Answer» -1, 90, 71, 52, 3 Given equation is:2x+y=7For x = - 1, we get−2+y=7⇒y=9\xa0∴\xa0(-1, 9) is a solution.\xa0For x = 0, we get⇒0+y=7⇒y=7\xa0∴\xa0(0, 7) is a solution.\xa0For x = 1, we get⇒2+y=7⇒y=5∴\xa0(1, 5) is a solution.\xa0For x = 2, we get⇒4+y=7⇒y=3\xa0∴\xa0(2, 3) is a solution.\xa0Hence, we have four solution\xa0(−1,9),(0,7),(1,5)and(2,3) |
