Question

Find three ordered pairs that satisfies the
following equation:
3x+2y=4​

Answer 1

see explanation

Explanation:

Rearrange the equation expressing x or y in terms of the other variable.

2y = 4 - 3x ( divide both sides by 2 )

y =
`(4-3x)/(2)`

Choose suitable values for x and evaluate for y

x = 2 → y =
`(4-6)/(2)` =
`(-2)/(2)` = - 1

Thus (2, - 1 ) ← is a solution

x = - 2 → y =
`(4+6)/(2)` =
`(10)/(2)` = 5

Thus (- 2, 5 ) ← is a solution

x = 4 → y =
`(4-12)/(2)` =
`(-8)/(2)` = - 4

Thus (4, - 4 ) ← is a solution
