Question

Determine the missing coordinate in the ordered pair (?,1/2) so that it will satisfy the given equation

Answer 1

Ok, so

We want to find the missing coordinate in the ordered pair, so that:

`5x-4y=17`

Given that the y-coordinate is 1/2, we could replace:

`\begin{gathered} 5x-4\cdot(1)/(2)=17 \\ \\ 5x-2=17 \\ 5x=17+2 \\ 5x=19 \\ x=(19)/(5) \end{gathered}`

Therefore, the coordinate in the ordered pair should be 19/5.
