• To use addition to solve inequalities • To use subtraction to solve inequalities. . .And Why To solve a problem involving safe loads, as in Example 4 Part 1 are inequalities with the same solutions. For example, x 1 4 , 7 and x, 3 are equivalent inequalities. You can add the same value to each side of an inequality,just as you did with ... Solve one-step inequalities Y.4. Solve two-step linear inequalities Y.5. Solve multi-step inequalities Linear equations. Z.1. Find the gradient of a graph ... Absolute Value inequalities are translated into "and" or "or" compound statements before they are solved. Therefore, the characteristics of the "and" / "or" statements learned in a previous lesson (see class notes titled “solve & graph compound linear inequalities) still hold true for both the algebraic expression and the graph.
Step 2: Write a let statement. What does our variable represent? Step 3: Write an equation: Step 4: Solve the equation: Step 5: Re-read the question. Does your answer make sense? Example 2: Alex rents a car for one day. The charge is $18 plus $0.12 per mile. Alex wants to spend exactly $30. How many miles can he drive? Step 1: Underline any key ...
