ONE STEP EQUATIONS Addition and Subtraction
/ / x + 6 - 6 - 6 x 2 = ONE STEP EQUATIONS Solve 6 + x = 8 x + 6 = 8 Commutative Property x + 6 = 8 x + 6 = 8 x + 6 / must also be done to the other side to keep it balanced. What you do to one side of the equation / - 6 - 6 x = 2
Check your answer!!!!!! 8 = 8 ONE STEP EQUATIONS 6 + x = 8 6 + 2 = 8 Rewrite original equation substituting our answer for x Original equation 6 + x = 8 6 + 2 = 8 Does our answer make the equation true? 8 = 8 Yes
/ / x - 4 + 4 +4 x 24 = ONE STEP EQUATIONS Solve 20 = x - 4 x - 4 = 20 Symmetric Property x - 4 = 20 x - 4 = 20 x - 4 / must also be done to the other side to keep it balanced. What you do to one side of the equation + 4 / +4 x = 24
Check your answer!!!!!! 20 = 20 ONE STEP EQUATIONS 20 = x - 4 Rewrite original equation substituting our answer for x 20 = x - 4 Original equation 20 = 24 - 4 Does our answer make the equation true? 20 = 20 Yes
REWRITE 3 + x = 11 10 = x - 2 x – 2 = 10 x + 3 = 11 12 = x + 7
ONE STEP EQUATIONS with Integers Solve x – 4 = -5 x - 4 = -5 / must also be done to the other side to keep it balanced. What you do to one side of the equation + 4 / +4 x = -1
Check your answer!!!!!! -1 – 4 = -5 -5 = -5 ONE STEP EQUATIONS Rewrite original equation substituting our answer for x x – 4 = -5 Original equation -1 – 4 = -5 Does our answer make the equation true? -5 = -5 Yes
ONE STEP EQUATIONS with Integers Solve x + 8 = 5 x + 8 = 5 / must also be done to the other side to keep it balanced. What you do to one side of the equation / - 8 -8 x = -3
Check your answer!!!!!! -3 + 8 = 5 5 = 5 ONE STEP EQUATIONS x + 8 = 5 Rewrite original equation substituting our answer for x x + 8 = 5 Original equation -3 + 8 = 5 Does our answer make the equation true? 5 = 5 Yes
ONE STEP EQUATIONS with Integers Solve -2 = x + 5 x + 5 = -2 / must also be done to the other side to keep it balanced. What you do to one side of the equation / - 5 - 5 x = -7
Check your answer!!!!!! -2 = -7 + 5 -2 = -2 ONE STEP EQUATIONS Rewrite original equation substituting our answer for x -2 = x + 5 Original equation -2 = -7 + 5 Does our answer make the equation true? -2 = -2 Yes
