Question

For the equation, complete the given ordered pairs.Need help solving the last order pair.

Answer 1

Hello!

First, let's remember:

In an ordered pair, we will have two variables represented as (x, y).

In the first two ordered pairs, the exercise informed the value of x. In the third ordered pair, it informs the value of y. We will solve it in a similar way, look:

`\begin{gathered} 4x-y=7 \\ 4x-7=7 \\ 4x=7+7 \\ 4x=14 \\ x=(14)/(4)=(7)/(2) \end{gathered}`

Answer:

x = 7/2 or also x = 3.5.
