Question 597303: Dividing a number by 3 is the same as subtracting 10 from twice the number. What is the number?
What I've done:
Let x be a number.
x / 3 = 2x - 10
(multiply 3 on both sides)
x = 2x - 30
(subtract 2x from each side)
-x = -30
(divide both sides by -1)
x = 30
Is this correct?

Question 597301: When a number is increased by 25, the answer is the same as doubling the sum of the number and 1. What is the number?
What I've done:
Let x be a number.
X + 25 = 2x + 1
(subtract 1 from both sides)
x + 24 = 2x
(subtract x from both sides)
24 = x
The number is 24.
Is this correct?
