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

How do you answer Ray bought 15 pencils for 7.75 Some cost 45 each the rest 65 each How many of each did Ray buy. Answer step by step please?
x= # of pencils that cost .45 y= # of pencils that cost .65 So now you need 2 equations for 2 variables: 15= x+y This equation is saying: 15 total pencils bought= pencils that cost .45 + pencils that cost .65 The second equation is: 7.75= .45x + .65y This equation is saying: total money spent (7.75)= price of pencils (.45) times # of pencils + price of pencils (.65) times # of pencils Then you combine these two equations, but first switch around the first equation to look like: y=15-x Then you replace the "y" in the second equation by putting in what y equals the first equation: 7.75= .45x + .65(15-x) Then distribute and solve for x: x = 10 Then enter 10 into the first equation for x to figure out y: y= 15- 10 y= 5 So your answer is-- Ray bought 10 pencils that cost .45 and 5 pencils that cost .65
