 4x + 3y =   6  ⇒ -24x - 18y = -36
-6x - 2y = -24 ⇒ <u>-24x -   8y = -96</u>
                                     <u>-10y</u> = <u>60</u>
                                      -10    -10
                                           y = -6
                              4x + 3(-6) = 6
                                  4x - 18 = 6
                                  <u>    + 18 + 18</u>
                                         <u>4x</u> = <u>24</u>
                                          4      4
                                            x = 6

The orderd pair (6, -6) is a solution of the system of equations.

Change x with 6 and y with -6

4x+3y=6
4*6+3*(-3)=24-18=<u>6</u>

-6x-2y=-24
-6*6-2*(-6)=-36+12=<u>-24
</u>
answer is yes

What is the answer to 3/x-2 is ≥12
Tju [1.3M]

Answer:

The answer to your question is 0 < x ≤ 3/14

Step-by-step explanation:

Here are the steps to solve it.

First, you need to solve your inequality step-by-step:

3/x −2 ≥ 12

-2x + 3/x = ≥12

Next, find the critical points of the inequality:

2x + 3/x = 12

−2x + 3 = 12x (Multiply both sides by x)

−2x + 3 − 12x = 12x − 12x (Subtract 12x from both sides)

−14x + 3 = 0

−14x + 3 − 3 = 0 − 3 (Subtract 3 from both sides)

−14x = −3

-14x/ -14 = -3/ -14 (Divide both sides by -14)

So, that gives you your answer:

x = 3/14
