Question

write four solution of linear
equations 2x+y=-3​

Answer 1

Answer:

$\huge\underline\bold\red{AnsWer}$

Given equation is:

2x+y=7

For x = - 1, we get

−2+y=7

⇒y=9

∴ (-1, 9) is a solution.

For x = 0, we get

⇒0+y=7

⇒y=7

∴ (0, 7) is a solution.

For x = 1, we get

⇒2+y=7

⇒y=5

∴ (1, 5) is a solution.

For x = 2, we get

⇒4+y=7

⇒y=3

∴ (2, 3) is a solution.

Hence, we have four solution (−1,9),(0,7),(1,5)and(2,3)

Answer 2

Step-by-step explanation:

Four linear equations 2x+y=-3

y=-3-2x

when x=0,y=-3-2*0=-3

when x=1,y=-3-2*1=-5

when x=2,y=-3-2*2=-7

when x=-1,y=-3-1*-1=1

Four solutions are (0,-3),(1,-5),(2,-7),(-1,1)
