The steps used to solve the equation 2x+8=20 for x are shown below. 2x+8=20 Step I: 2x=12Step II: x=6Which property makes step I true?Division property of equalityReflexive property of equalitySubtraction property of equalitySymmetric property of equality
Solution
The property that makes Step I true is the Subtraction property of equality. This property states that if you subtract the same number from both sides of an equation, the equation remains true. In this case, 8 was subtracted from both sides of the equation 2x + 8 = 20 to get 2x = 12.
