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

Answer:

The number is 10/3

Step-by-step 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
