x = 10/3
3(x +10) = 20
3x + 30 = 20
-30. -30

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
