Question

2x + 3y = 13

Step 2 of 2: Determine the missing coordinate in the ordered pair (?, 3/2) so that it will satisfy the given equation

Answer 1

`(17)/(4)`

Explanation:

Replace y with 3/2 and solve for x

2x + 3(3/2) = 13

2x + 9/2 = 13 Subtract 9/2 from both sides

2x =
`(13)/(1)` -
`(9)/(2)`

2x =
`(26)/(2)` -
`(9)/(2)`

2x =
`(17)/(2)` Divide both sides by 2

x =
`(17)/(2)` ÷
`(2)/(1)`

x =
`(17)/(2)` x
`(1)/(2)`

x =
`(17)/(4)` o r4
`(1)/(4)` or 4.25
