Answer:

18 people

Step-by-step explanation:

Let the number of people at the party before the arrival be x

20% of x = 3

20/100 * x = 3

20x = 300

x = 300/20

x = 15

Adding the friends , we have 15 + 3 = 18

Solve each system by elimination by multiplying both equations. Eliminate "y" first. Show all work.
Damm [24]
We have the 2 equations
1- ) 5x-8y=6
2-) -6x-3y=18
multiplying the first equation by 3 and the second equation by 8 then subtracting
1-) 15x-24y=18
2-) -48x-24y=144

-48x-24y=144
(-) 15x-24y=18
-------------------------------------
-63x = 126
x=-2
substituting in equation 1
5(-2)-8y=6
-10-8y=6
-8y=16
y=-2
the soultion is (-2,-2)
