Question

write two solutions of equation 2x+y equal to 7 ​

Answer 1

2x+y=7 2 x + y = 7 are (0,7), (1,5), (2,3), (3,1). Hence, four solutions for equation x=4y x = 4 y are (0, 0), (1, 4), (-4,-1), (8, 2).

Answer 2

Answer:

$2x + y = 7$

$</strong><strong>L</strong><strong>et \: x = 0$

$2(0) + y = 7$

$y = 7$

$</strong><strong>L</strong><strong>et \: x = 1$

$2(1) + y = 7$

$y = 7 - 2$

$y = 5$

Two solutions are (0,7) and (1,5).
