Question

5x - 4y = 17Step 2 of 2: Determine the missing coordinate in the ordered pair (?, -3) so that it will satisfy the given equation,

Answer 1

The equation is given as,

$5x-4y=17$

Let the unknown x-coordinate be 'a', then the ordered pair will be,

$(a,-3)$

It is required that this ordered pair satisfies the equation,

$\begin{gathered} 5(a)-4(-3)=17 \\ 5a+12=17 \\ 5a=5 \\ a=1 \end{gathered}$

Thus, the missing coordinate in the ordered pair is 1.
