Question

Three times a number increased by ten is equal to twenty

Answer 1

the wording is a little confusing so it could be either of these answers.

3x + 10 = 20

-10. -10

3x = 10

x = 10/3

3(x +10) = 20

3x + 30 = 20

-30. -30

3x = -10

x = -10/3

Answer 2

The number is 10/3

Explanation:

Step 1: Convert words into an expression

Three times a number increased by ten is equal to twenty

(3n) + 10 = 20

Step 2: Subtract 10 from both sides

3n + 10 - 10 = 20 - 10

3n = 10

Step 3: Divide both sides by 3

3n / 3 = 10 / 3

n = 10/3

Answer: The number is 10/3
