15 pens. 5 pencils.
this is a simple question that requires a little bit of substitution. before making hte 2 equations, we need to define our two unknowns, so let x= cost of pens y= cost of pencils therefore 15x + 20y= 20x = 15y -5x = -5y therefore x=y Hence, the cost of the pens and the pencils is the same.
4x + 3y = 5.60 2x + 3y = 4.60 4x + 3y = 5.60 -2x - 3y = -4.60 ------------------------ 2x = 1.00 x = .50 <==cost of pencil 2x + 3y = 4.60 2(.50) + 3y = 4.60 1 + 3y = 4.60 3y = 3.60 y = $1.20 <==cost of pen Pencils are $.50 and pens are $1.20 <==ANSWER
I HAVE THAT SAME PROBLEM! Let me guess, Keeping Skills Sharp. Wait, Where do you go to school?
Well, you write with both of them...
