If you would like to solve for the positive value of x, you can do this using the following steps:
6 * x^2 - 54 = 0 /6
x^2 - 9 = 0
(x - 3) * (x + 3) = 0
1. x = 3
2. x = - 3
The correct result would be x = 3.
Susanne will be x because both people use her as a comparsion. Bob's expression would be 4x, and Dakota's expression would be x - 3. If Dakota's and Bob's age sum is 93 then form the equation 4x + x - 3 = 93 to find Susanne's age. I'll do the steps below.
4x + x - 3 = 93
5x - 3 = 93
5x = 96
x = 19.2
Answer:
-17x-3
Step-by-step explanation:
Distribute the negative to the second part of the equation. remove the parenthesis from the first part and then add like values.
-4x-2-13x-1
-4x-13x-2-1
-17x-3
