Question

Translate the sentence into an equation.

Twice the sum of a number and 2 is equal to 8.
Use the variable w for the unknown number.

Answer 1

2(w + 2) = 8

Hope this helps.

Answer 2

2(x + 2) = 8

The sum of number and 2 means adding a variable and 2. Twice means to multiply that by 2. And equal to 8 is self explanatory.
