First you need to multiply by a factor that will givr you the same value in one of the x or y value.
(6x-12y=24)1
+(-x-6y=4)-2
6x-12y=24
=2x+12y=-8
8x=16÷8
x=2
now that you have x, substitute x by 2 in one of the eqauations
-2-6y=4
+2. +2
=-6y=6
÷-6. ÷-6
y=-1
The greatest common factor is 8x:
8x² - 24xy + 16x = 8x ( x - 3y + 2)

Answer: $48
Step-by-step explanation: The amount of money Joe made can be divided by 9. 54/9 = 6. Joe made 9 dollars six times so Leila made 8 dollars 6 times. 6 x 8 = 48.
You can open the brackets because it is addition
x+5+2x+3
after rearranging
x+2x+5+3
=3x+8
