Answer:
2(x + 6) = 38
Step-by-step explanation:
First, we choose a variable to represent the unknown number.
1. Let x = the unknown number.
Then, we translate the sentence into an equation using the variable we chose.
"Twice the sum of six and a number is 38."
We do it piece by piece:
"the sum of six and a number": x + 6
"Twice the sum of six and a number": 2(x + 6)
"Twice the sum of six and a number is 38.": 2(x + 6) = 38
Now we have an equation that represents the sentence.
2(x + 6) = 38
