Sam claims that the solution to 10x-1/2 (4x+20)=30 is x=5 she wants to prove this claim using the four assumptions below  Look at the picture pls

Answer is in a photo. I can't attach it here, but I uploaded it to a file hosting. link below! Good Luck!

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
