How can you get 3 1/2x alone on the left side of the equation 3 1/2 x + 215 = 495? what is the resulting equation?

subtract 215 from both sides

x = 80

Step-by-step explanation:

to get the 3 1/2 x alone subtract 215 from both sides.

this moves it to the other side.

495-215 =280

3 1/2 x = 280

divide both sides by 3 1/2

this will solve for x

x = 80

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.

(-1,-0.5)
