Exercises Equations and inequalities

Example 8.9 from Prealgebra, 8.1 Solve Equations Using the Subtraction and Addition Properties of Equality

Solve Equations Using the Subtraction and Addition Properties of Equality: example 8.9

Translate and solve: five more than $x$ is equal to $26 .$

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

Translate.

Subtract 5 from both sides.

Simplify.

Check:
Is $26$ five more than $21$ ?

The solution checks.

Your turn

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

Translate and solve: Eleven more than $x$ is equal to $41 .$
