... Rounding Error—rounded solutions are not exactly correct and will have error Solve decimal equations the same as normal equations, except solution may be rounded: Ex. 17 = 48 – 6x given equation 17 – 48 = 48 – 48 – 6x Subtraction Property of Equality -31 = -6x simplify by combining like terms -31/-6 ...

... Given a, b, h ℝ where a and b are not both zero, the equation ax + by = h is called a linear equation in two variables. The symbols x and y are called variables, the numbers a and b are called coefficients , and the number h is called the right hand side constant. An ordered pair (x0 , y0 ) of rea ...

... A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables. Now consider the following tw ...
