[tex] 2x+3 [/tex]
You are taking two times a number, which is defined as x. That is equivalent to 2x. Then, you are adding three more to that product.
Writing an equation based on a sentence depends on the mathematical phrases in the sentence. 3 + 2x. 3 more is 3 + and than the product of two and a number x is 2x. So 3 + 2x.
