Are you thinking, "$x$ could be four"? 1. INEQUALITIES, NUMBER LINES, AND INTERVAL NOTATION. x-intercepts and y-intercepts. Example 4.2.1 (A very, very simple example). 6. Verdana \\ a = \frac { - 1 } { - 5 } = \frac { 1 } { 5 } \end{aligned}\). Subtracting $7$ from each side and dividing each side by positive $5$ results in an inequality that is true. To do this, use the addition or subtraction property of equality to place like terms on the same side so that they can be combined. PScript5.dll Version 5.2 Do not try to clear fractions when simplifying expressions. Solve: $\frac { 5 } { 3 } x + 2 = - 8$. (Note that this will open a different textbook in a new window. The process is similar to solving linear equations. Always use the original equation to check to see if the solution is correct. Solve: $\frac { 1 } { 3 } x + \frac { 1 } { 5 } = \frac { 1 } { 5 } x - 1$. If solving a linear equation leads to a false statement like $0 = 5$, then the equation is a contradiction and there is no solution, .
