10 - 2x = -5x -5
+2x +2x
10 = -3x -5
+5 +5
15= -3x
X= -5

First you add 5x on both sides:

10−2x+5x=−5

=
10+3x=−5

Then you subtract 10 from both sides:

3x=−5−10
=
3x=-15

Then you divide both sides by 3

X= -15/3

X= -5

G = F(4x+5)/ 3x-2
C = (4x+5) (3x-2)/ 24C
F = 3x-2/C

I don't understand how to do this, could I have some help?

kondaur [170]

Step-by-step explanation:

step 1. slope = rise/run

step 2. the rise is the height between any 2 points

step 3. the run is the distance left or right between the same 2 points

step 4. if the line goes up "left to right" the slope is positive, down it is negative

step 5. slope = + 6/2 = 3.
