Given:

y = 4x - 9 

Complete the missing value in the solution.

Solution:

In order to complete the missing value, we solve for the value of x. Start first by equating the value of y to 0 and then transpose -9 on the other side of the equation. Note that when transposing a number, the sign changes.

4x - 9 = 0

4x = 9

Divide both sides by 4 in order to get the value of x.

4x/4 = 9/4

x = 9/4 or 2.25

Final answer:

9/4 or 2.25
