Question

Write the sentence as an equation and solve. Twice the difference between 5 times a number and 6 is 18. please help!​

Answer 1

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.
