Equation in One VariableDate: 04/13/97 at 15:13:33 From: steph Subject: Adding and Subtracting Terms 14a + 3 = 11 - 2a - 2a = 2a _________________ 12a + 3 = 11 Is this right so far and how do you complete this equation? Date: 04/13/97 at 18:06:02 From: Doctor Steven Subject: Re: Adding and Subtracting Terms No. Actually, you needed to add 2a to both sides instead of subtracting. You should get: 14a + 3 = 11 - 2a + 2a = 2a _________________ 16a + 3 = 11 - 3 = - 3 _________________ 16a = 8 Then divide both sides of the equation by 16 to get: a = 8/16 = 1/2. Hope this helps. -Doctor Steven, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
