Unformatted text preview: solve these kinds of equations in the previous section. First we need the logarithm on one side by itself with a coefficient of one. Once we have it in that form we convert to exponential form and solve. 2 æEö 5.9 = log ç 4.4 ÷ 3 è 10 ø æEö 8.85 = log ç 4.4 ÷ è 10 ø E 108.85 = 4.4 10 8.85 E = 10 (104.4 ) = 1013.25 So, it looks like there would be a release of 1013.25 joules of energy in an earthquake with a magnitude of 5.9. © 2007 Paul Dawkins 314 http://tutorial.math.lamar.edu/terms.aspx College Algebra Systems of Equations Introduction This is a fairly short chapter devoted to solving systems of equations. A system of equations is a set of equations each containing one or more variable. We will focus exclusively on systems of two equations with two unknowns and three equations with three unknowns although the methods looked at here can be easily extended to more equations. Also, with the exception of the last section we will be dealing only with systems of linear equations. Here is a...
