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
