Answer:

The answer is (7,3)

Step-by-step explanation:

to solve this systems of equations, set both equations equal to y (common variable in both equations).

$24-3x=y\\3=y$

by looking at both of these, we already know that y is equal to 3.

substitute y for 3 to solve for x.

$24-3x= 3$

subtract 24 from both sides.

$-3x= -21$

divide both sides by -3.

$x=7$

the ordered pair will be written as (7,3)

you can check your answer by substituting 7 and 3 for x and y.

$24= 3(7)+3\\24=21+3\\24=24$

hope this helps ;)
