Chapter 2: Problem 5

Translate each statement into an equation and then solve the equation for the unknown number. Fifteen subtracted from a number is 45.

Short Answer

Expert verified
Answer: The unknown number is 60.

Step by step solution

01

Define the unknown number

Let's call the unknown number "x".
02

Translate the statement into an equation

The statement says "Fifteen subtracted from a number is 45." In equation form, this is: x - 15 = 45
03

Solve the equation for the unknown number (x)

We can solve the equation x - 15 = 45 by isolating x. To do this, we add 15 to both sides of the equation: x - 15 + 15 = 45 + 15 x = 60 The unknown number, x, is equal to 60.
