Answer:
The number is 10/3
Step-by-step explanation:
<u>Step 1:  Convert words into an expression</u>
Three times a number increased by ten is equal to twenty
(3n) + 10 = 20
<u>Step 2:  Subtract 10 from both sides</u>
3n + 10 - 10 = 20 - 10
3n = 10
<u>Step 3:  Divide both sides by 3</u>
3n / 3 = 10 / 3
n = 10/3
Answer:  The number is 10/3
