2x-3y=5
determine the missing coordinate in the ordered pair −3) so that it will satisfy the given equation.

x=-2

Step-by-step explanation:

So because you have (?,-3), the -3 is your y axis.

Remember (x,y).

So, you would substitute your y with the -3.

Ex. 2x-3(-3)=5

You will solve from there

-3 x -3 = 9

2x+9=5

subtract your 9 from your 5

2x=-4

divide your 2 from your -4

x=-2
