The product of 3 and the sum of a number and 10 is 42

The number is 4

Step-by-step explanation:

[] Underlined means it is turned into a mathematical statement in the next line

-> Let n be "a number"

The product of 3 and the sum of a number and 10 is 42

The product of 3 and the sum of a number and 10 is 42

The product of 3 and the sum of a number and 10 = 42

The product of 3 and n + 10 = 42

3(n + 10) = 42

[] Now we can solve for n

3(n + 10) = 42

3n + 30 = 42

3n = 12

n = 4

3*(n+10)= 42

Step-by-step explanation

1. Product means the whole thing it multipling
2. The sum of n (a number) and 10 means n+10
3. Put it together and you get 3*(10+42)

4. Parenthesis because the sum is getting multiplied

5. For when it says a number you means you put a variable there.
