Question

If 4x + 15 =27 find the value of 6x-9

Answer 1

9

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:

`4x + 15 = 27\\4x=27-15\\4x=12\\x=(12)/(4)\\x=3`

Now we replace "x" with "3" in the expression:

6x - 9

= 6(3) - 9

= 18 - 9

= 9
