Work Step by Step

Lets translate English terms into mathematics terms. Is in english means equal in math, which result in =72 on one side of the equation. Twice the number, lets say the number we are talking about is x, means it is 2 times the number x; resulting in 2x. Six more means that it is we would add six in the equation on the side of the term 2x. Resulting in equation 72 = 2x +6. We can also rearrange the equation in way that results in 6 + 2x = 72.
