  1. SOLVING ONE STEP EQUATIONS USING ADDITION OR SUBTRACTION STEP 1: Identify the Original Operation STEP 2: Perform the Inverse Operation. STEP 3: Do this to BOTH Sides to keep equation balanced. STEP 4: SOLVE / SIMPLIFY Equation STEP 5: CHECK YOUR WORK! - 6 - 6 C = 1 – 6, therefore C = -5 PLUG ANSWER BACK INTO ORIGINAL EQUATION - 5 + 6 = 1 It works! ANSWER: C = -5

  2. SOLVING ONE STEP EQUATIONS USING ADDITION OR SUBTRACTION STEP 1: Identify the Original Operation STEP 2: Perform the Inverse Operation. STEP 3: Do this to BOTH Sides to keep equation balanced. STEP 4: SOLVE / SIMPLIFY equation STEP 5: CHECK YOUR WORK! + 6 + 6 f = 6 + 6, therefore f = 12 PLUG ANSWER BACK INTO ORIGINAL EQUATION 12 – 6 = 6 It works! ANSWER: f = 12

  3. SHOW ALL WORK USING INVERSE OPERATIONS

  4. SOLVING ONE STEP EQUATIONS USING MULTIPLICATION OR DIVISION STEP 1: Identify the Original Operation STEP 2: Perform the Inverse Operation. STEP 3: Do this to BOTH Sides to keep equation balanced. STEP 4: SOLVE / SIMPLIFY equation STEP 5: CHECK YOUR WORK! 5 ÷5 C = 85 ÷ 5, therefore C = 17 PLUG ANSWER BACK INTO ORIGINAL EQUATION 5 x 17 = 85 It works! ANSWER: C = 17

  5. SOLVING ONE STEP EQUATIONS USING MULTIPLICATION OR DIVISION STEP 1: Identify the Original Operation STEP 2: Perform the Inverse Operation. STEP 3: Do this to BOTH Sides to keep equation balanced. STEP 4: SOLVE / SIMPLIFY equation STEP 5: CHECK YOUR WORK! 12 x 12 r = 4 x 12, therefore r = 48 PLUG ANSWER BACK INTO ORIGINAL EQUATION 48 ÷ 12 = 4 It works! ANSWER: r = 48

  6. SHOW ALL WORK USING INVERSE OPERATIONS
