What is the answer to 6a + 6c =126

Step-by-step explanation:

You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.

6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23.  Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
