Don’t you just love inequalities?  Of course I can only hear you saying “not really…inequalities stink!”  Well I know you may not like inequalities but you need to know how to work with them.   All right let me stress some points:

* the solution to an inequality is more than a single number;  inequalities have solution sets (many/infinite number of solutions).   As an example lets consider the inequality   x > 5  what can the value of x be?  i.e. what numbers are greater than 5? clearly an infinite amount of numbers are greater than 5 so we need to express the solutions to inequalities in a different way other than writing out all the numbers greater than 5 – that would take a lot of paper and with global warming….you get the idea.    So to deal with this little issue we graph the solution of an inequality on a number line.

other important points:

*  we simplify inequalities using the same steps as solving equations

* when dividing/multiplying both sides of an inequality by a negative number you need to reverse the inequality symbol; example  >  would turn into < .

* when graphing your solution <, > symbols use open circles;  <=,  >= symbols fill in the circle.

* make sure you can solve linear equations before taking on inequalities- good luck and may the force be with you!!

A video game system and several games are sold for $652. The cost of the games is 3 times as much as the cost of the system. Fin
vesna_86 [32]

Answer:

The cost of the system is $163 and The cost of the games is $489

Step-by-step explanation:

∵ A video game system and several games are sold for $652

∵ The cost of the games is 3 times as much as the cost of the system

→ Assume that the cost of the system is $x

∵ The cost of the system = x

∴ The cost of the games = 3 × x = 3x

∵ The total cost of the system and the games = 652

→ Equate the sum of the cost of the system and the cost of the games

   by 652

∴ x + 3x = 652

→ Add the like terms in the left side

∴ 4x = 652

→ Divide both sides by 4 to find x

∵ \frac{4x}{4}=\frac{652}{4}

∴ x = 163

∵ The cost of the system = x

∴ The cost of the system is $163

∵ The cost of the games = 3x

∴ The cost of the games = 3(163) = 489

∴ The cost of the games is $489

Solve for x and y<br> 7x - 3y =23<br>2x - 4y = -8<br>​
dybincka [34]

Q. 7x - 3y =23

Lets,   \: Find  \: x :-

7x - 3y = 23

7x - 3(0) = 23

x = 3.286

Now, Lets \:  find  \: y :-

7x - 3y = 23

7(0) - 3y = 23

y \: = -7.667
