Twice the difference between 5 times a number and 6 equals 18:
2(5x-6)=18
We need to solve for x:
5x - 6 = 2(difference) = 18
The difference must equal 9.
In order for the difference to equal 9, x must equal 3.
5(3) - 6 = 2(difference) = 18
Let's solve:
15 - 6 = 2(9) = 18
Therefore, in this equation, x = 3.
