Don't forget to read the information provided in the university's home page. 60 is our initial value, .5 is our rate, and the distance will be the exponent (which tells you how much the rate compounds). We may be asked to combine like terms and distribute coefficients when solving. Like linear equations, you can solve a linear inequality by using algebra to isolate the variable. On the right-hand side I'm gonna get ax. First, we solve for 2x - 2 > 20. Contents. A strong understanding of math is essential for success in many different fields. To see this page as it is meant to appear, please enable your Javascript! I'm gonna get nine x. A linear equation with one variable 130, \(x\), is an equation that can be written in the standard form \(ax + b = 0\) where \(a\) and \(b\) are real numbers and \(a 0\).For example \(3 x - 12 = 0\) A solution 131 to a linear equation is any value that can replace the . If the equation has both fraction coefficients and fraction constants, consider getting rid of the fractions in the first step. So how could I have an infinite number of solutions, an equation So let's see what we could do with this thing right over here. "Undo" the operations surrounding the variable so that you can get it by itself on one side, and then that becomes your answer.
