  4. Warm up Objective I will be able to solving two-step equations using inverse operations. If an equation has two operations, use inverse operatins and work backwards to undo each operation one at a time. (Think PEMDAS backwards or SADMEP) First: add or subtraction Second: multiply or divide Notes
