Step 1 Eliminate fractions by multiplying all terms by the least common denominator of all fractions. You would probably think that at least means less than. Thus we obtain Remember, abx is the same as 1abx. This graph represents every real number less than 3. Prefer to meet online? Notice that as soon as we divide by a negative quantity, we must change the direction of the inequality.

Then follow the procedure learned in chapter 2.

Solution First make a table of values and decide on three numbers to substitute for x. A system of two linear equations consists of linear equations for which we wish to find a simultaneous solution.

Such first-degree equations are called linear equations. Let us try an example: Notice that since we are dividing by a negative number, we must change the direction of the inequality.

To express the slope as a ratio we may write -3 as or. This graph represents the number 1 and all real numbers greater than 1.

Example 1 Solve for c: Solution We reason in this manner: A graph is used to communicate a statement. Thus we obtain Remember, abx is the same as 1abx.

Solution Note that the graph has an arrow indicating that the line continues without end to the left. If an equation is in this form, m is the slope of the line and 0,b is the point at which the graph intercepts crosses the y-axis.

The example above was a system of independent equations. Then substitute the numerical value thus found into either equation to find the value of the other unknown. Independent equations The two lines intersect in a single point.How to Use the Calculator. Type your algebra problem into the text box.
