equations that must be solved. Systems of nonlinear equations are typically solved using iterative methods that solve a system of linear equations during each iteration. We will now study the solution of this type of problem in detail. The basic idea behind methods for solving a system of linear equations is to reduce them to linear equations ...For example, 0.3 = and 0.17 = . So, when we have an equation with decimals, we can use the same process we used to clear fractions—multiply both sides of the equation by the least common denominator. Example : Solve: 0.8x − 5 = 7. Solution. The only decimal in the equation is 0.8. Since 0.8 = , the LCD is 10.Solving Systems of Linear Equations To solve a system of linear equations a 11x 1 + a 12x 2 + + a 1nx n = b 1 a 21x 1 + a 22x 2 + + a 2nx n = b 2..... a m1x 1 + a m2x 2 + + a mnx n = b m we use elementary operations to convert it into an equivalent upper triangular system; equivalent SLEs have exactly the same solution set.Theorem 1 (Equivalent Systems) A second system of linear equations, obtained from the rst system of linear equations by a nite number of toolkit operations, has exactly the …Consider the linear system. fThe idea is to keep the first equation and work on the last two. In doing that, we will. try to kill one of the unknowns and solve for the other two.
