Example 2.39 from Prealgebra, 2.3 Solving Equations Using the Subtraction and Addition Properties of Equality

Solving Equations Using the Subtraction and Addition Properties of Equality: example 2.39

Translate and solve: The difference of $y$ and $14$ is $18 .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

The difference of y and 14 is 18.

Translate.

Add 14 to both sides.

Simplify.

We can check. Let $y = 32$ .

So $y = 32$ is the solution.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Translate and solve:

The difference of $z$ and $17$ is equal to $37 .$
