Answer:
9
Step-by-step explanation:
To find the value of the expression "6x - 9", we would first need to find the value of "x" and then replace and solve.
The equation we are given is:
4x + 15 = 27
We can solve this by taking the numbers to one side and solving for the variable "x", shown below:
[tex]4x + 15 = 27\\4x=27-15\\4x=12\\x=\frac{12}{4}\\x=3[/tex]
Now we replace "x" with "3" in the expression:
6x - 9
= 6(3) - 9
= 18 - 9
= 9
