Answer:

Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28

Step-by-step explanation:

Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667

Can someone please do this for me
Natasha_Volkova [10]
Next time please indicate which problem you want to work on.

One example of an equation with variables present on both sides is

y-b = m(x-a).  Given the slope of a line and one point (a,b) through which the line passes, you can come up with an equation of the line.

Or, given the numeric value of y-b and that of x-a, you could obtain the slope of the line thru the points (x,y) and (a,b).
