We show all the solutions to the inequality \(x>3\) on the number line by shading in all the numbers to the right of three, to show that all numbers greater than three are solutions. The coefficients of linear equations may be any real number, even decimals and fractions. First, use the appropriate equality property of addition or subtraction to isolate the variable term.

Therefore, displaying these steps in this text, usually in blue, becomes optional. To illustrate the problem, consider the true statement \(10 > 5\) and divide both sides by \(5\). We solve algebraic equations by isolating the variable with a coefficient of 1. For example: \[\begin{align*}10 &> - 5 \\[4pt] Even though the College Ready Packets were meant to prepare students for college entrance exams, they can be useful for any secondary math class as review material. \\ 5 x + 3 & = 3 x - 15\quad\quad\quad\color{Cerulean}{Solve.} Equations and inequalities can be represented on a number line. 1.2 Notes: Solving Linear Equations. Translating algebraic phrases in words to algebraic expressions Knowing the language of algebra can help to extract meaning from word problems and to situations outside of school. If you have a linear inequality in slope intercept form, you can use these steps to graph that inequality on the coordinate plane: Identify the y-intercept constant in the inequality (the 'b' term in the equation) Plot the y-intercept point on the coordinate plane at the (0,b) point. A solution131 to a linear equation is any value that can replace the variable to produce a true statement. Let's start owith a very, very simple example.
