Linear Equations:Linear equations are the equations, which are in the first order. In general, linear equations describe the equations of straight lines. The graph of the linear equation is always a straight line. We have linear equations in one variable and linear equations in two variables, a...
As the examples have shown, we can perform the same operations on both sides of an inequality, just as we do with equations; we combine like terms and perform operations. To solve, we isolate the variable.Example: Solving an Inequality Algebraically Solve the inequality: 13−7x≥10x−...
Linear Equations in One VariableA linear equation in one variable is anequation that can be rearranged to havethe form ax + b = 0 where a and b are realnumbers with a ≠ 0.Examples of linear equations in one variable:5x + 4 = 2 + 3x simplifies to 2x + 2 = 01(x – 3) + 4...

be any number and it would not affect the equation. This graph will be a horizontal line. This makes sense, because the x axis isy = 0and the y axis isx = 0. Solutions of Equations in Two Variables We have seen expressions and equations of one variable, mainly x. Here is an expres...
Solving one-variable linear inequalities is almost exactly like solving the one-variable linear equations. But, where the solutions to linear equations are single values, the solutions to linear inequalities are infinite intervals.Rather than having, say, a solution of "x = 2" for a linear ...
Explain one solution, no solution, and infinitely many solutions graphically with three planes Explain one solution, no solution, and infinitely many solutions algebraically when solving a system of three variable linear equations Linear Equations in Three Variables A linear equation in one variable, wh...
Pattern for solving linear equations in 1 variable: Get it READY to solve: 1. Distribute to clear parentheses 2.Multiply to clear fractions and decimals 3. Combine like terms . Now it is ready, so SOLVE it : 1. Get variable on only one side using addition principle 2. Get constants...
