Translate the sentence into an equation. Twice the difference of a number and 4 equals 5. Use the variable x for the unknown number.

2 (x - 4) = 5

Step-by-step explanation:

Twice the difference means multiply by 2

"The difference of a number and 4" mean subtraction, a number here is 'x', so this translates to x - 4

"Twice the difference of a number and 4" means doulbe the difference of x and 4, so we get

2 (x - 4)

"equals" means an equals sign, the equation is equal to 5, so we have ...

2 (x - 4) = 5

2 (x-4) = 5

Step-by-step explanation:

2 (x-4) = 5 since the difference of a number and 4 translates to x-4 and twice the difference translates to 2 (x-4).
