5x−2y=30 complete the missing value in the solution to the equation. (8, )

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

5x−2y=30
 5x−30=2y
 Substituting the value x = 8
 5(8)−30=2y
 40-30=2y
 10=2y
 y=10/2=5
 the missing value in the solution to the equation is 5
 the point is: 
 (8,5)

What do you mean i don’t understand
