The expression "eight more than twice a number" can be written as 2x + 8, where x represents the unknown number. This expression indicates that you should first multiply the number by 2 and then add 8 to the result. For example, if the number is 5, then 2(5) + 8 = 10 + 8 = 18.
When the numerator is less than the denominator. For example 1/2, 3/4, 18/27, ...
4x+x+18 = 14
Yes. (If you subtract -17 minus -18 on a calculator, you get a positive number.)
N = (6*(a 2 )) -18
