WILL GIVE BRAINLIEST!! This is a story problem. You may use the method of your choice to solve the problem. (substitution, combination, elimination ) The sum of 2 numbers ( x and y ) is +12 The difference of the same 2 numbers is -4 1. Which method will you use and why? 2. How will you set up the equation needed to solve? 3. What is the solution expressed as an ordered pair? (x, y)

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.

i think the amount would be $140.62

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
