What are the Rules for Solving Inequalities? Lesson Summary Frequently Asked Questions How do you solve an inequality in math? 1. Combine all variables 2. Isolate the variable Remember when working with inequalities to do the same operations on both sides of the inequality. And, when multiplying...
We must reverse the inequality whenever we multiply or divide both members of an inequality by a negative number. TRANSLATING WORD SENTENCES Most problems that deal with practical applications of mathematics are expressed in words. Before we can solve such problems, we must translate word sentences ...
Equations may be true or false, just as word sentences may be true or false. The equation: 3 + x = 7 will be false if any number except 4 is substituted for the variable. The value of the variable for which the equation is true (4 in this example) is called the solution of the...
The first inequality (I assume that these are separate problems) is 10x -2 < 5x + 13 so let's collect like terms; we get 5x < 15. We divide by 5 to get x < 3. In interval notation, the solution is (-infinitiy, 3). Upvote • 0 Downvote Add comment Still looking for help...
