Question

for the given equation 2x+y=7 find values of 0,1,2,3.​

Answer 1

Answer:

2x + y = 7

Changing the subject of the equation to y, and solving, we get,

∴ y = 7 - 2x

Let us now take different values of x and substitute them in the given equation.

For x = 0, we get y = 7 - 2 (0) ⇒ y = 7. Hence, we get ( x, y ) = (0, 7)

For x = 1, we get y = 7 - 2 (1) ⇒ y = 5. Hence, we get ( x, y ) = (1, 5)

For x = 2, we get y = 7 - 2(2) ⇒ y = 3. Hence, we get ( x, y ) = (2, 3).

For x = 3, we get y = 7 - 2(3) ⇒ y = 1. Hence, we get ( x, y ) = (3, 1).

Therefore, four solutions of the given equation are (0, 7), (1, 5), (2, 3) and (3, 1).
