4x−3y=18 Step 2 of 2 : Determine the missing coordinate in the ordered pair (?,12) so that it will satisfy the given equation.

Answer:

13.5

Step-by-step explanation:

The point with the missing coordinate is (?, 12), so the value of y is 12. Plug 12 into the equation in the place of y.

4x - 3(12) = 18

4x - 36 = 18

4x = 54

x = 54/4 = 13.5
