Answer 1

x = 10.

Explanation:

Given: Two times the sum of 5 and some number is 30. What is the number?

First, write the equation:

2(5 + x) = 30

Simplify the brackets with distribution property:

10 + 2x = 30

Then collect like terms:

2x = 30 - 10

Finally, calculate:

2x = 20 (Divide both sides by 2)

x = 10

Answer 2

10

Explanation:

5+10=15

15×2=30

so the answer to your question is 10
