Homework Questions?

Essential Questions How do I solve an equation for a given variable? (These are called “literal equations.”) How do I solve inequalities?

Notes Solving literal equations means getting the variable of interest all by itself. You simply “undo” all of the operations to get the variable alone. Example: Solve the following equation for b1 HOW???

Literal Equations You have to get the b1 by itself. That means we need to move the ½, the h, and the b2 to the other side. Undo each operation.

Practice Solve each equation below for g:

Solving Inequalities This is like solving an equation with the following exceptions: You have one of the following operators instead of “equals” ≤, ≥, <, OR > When you multiply or divide to solve an inequality, you have to flip the sign of the inequality: e.g.
