Question

Find
four
solutions of
of 2x +y = 7​

Answer 1

Answer:

put x=0

2x+y=7

2×0+y=7

0+y=7

y=7

then

put y=7

2x + y =0

2x + 7=0

7 = ‐ 2x

x = -7/2

Answer 2

$\huge\sf\red{2x+y=7}$

$\large\sf{put\:x=0=2×0+y=7=y=7}$

$\large\sf{put\:x=1=2×1+y=7=y=5}$

$\large\sf{put\:x=2=2×2+y=7=y=3}$

$\large\sf{put\:x=3=2×3+y=7=y=1}$

$\huge\sf\purple{Solutions\:are;-}$

$\large\sf{x=0,y=7}$

$\large\sf{x=1,y=5}$

$\large\sf{x=2,y=3}$

$\large\sf{x=3,y=1}$
