So you have:
\frac{3}{x} + 2  =  \frac{2}{x} - 1


1) Start off by multiplying both sides by x to simplify the problem:
\frac{3}{x} + 2 = \frac{2}{x} - 1 \\
x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\
3 + 2x = 2 - x


2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
3 + 2x = 2 - x\\
3x = -1

3) Finally, divide by 3 on both sides to find the value of x:
3x = -1\\
x =  \frac{-1}{3}

------

Answer: x = \frac{-1}{3}

-4x+-6y=24 how do you solve?
alina1380 [7]
So,

Let's manipulate this into the y=mx + b form.

Add 4x to both sides
-6y = 4x + 24

Divide both sides by -6
y =  \frac{4}{-6} x - 4

Just use the slope to find the points you need.

The y-intercept is (0,-4).

The slope is \frac{4}{-6}.  Finding the next point:
(-6,0)

You could have also used the <em>slope intercept method.</em>

-4(0) - 6y = 24
-6y = 24

Divide both sides by -6
y = -4
(0,-4)


-4x - 6(0) = 24
-4x = 24

Divide both sides by -4
x = -6
(-6,0)

-2(x - 5) = -14 PLEASEEEEE HELPPPPPP
juin [17]
Okay so you need to start off by using the distributive property, meaning you are going to multiply -2 by both items within the parentheses. this gives you -2x + 10 = -14. from here you want to isolate x, so you’ll subtract both sides by 10 to move it to the other side. this gives you -2x=-24. then you’ll divide both sides by -2 to completely isolate x. this gives you x=12. does that make sense?
