math question?!?!?

x = pencils y = pens

4x + 2y = .74 _____ Equation 1

6x + 5y = 1.53 ____ Equation 2

Step 1: Eliminate a variable

Equation 1 X 3:

12x + 6y = 2.22

Equation 2 X 2:

12x + 10y = 3.06

Subtract the two:

12x + 6y - (12x + 10y) = 2.22 - 3.06

12x - 12x + 6y - 10y = -.84

-4y = -.84

y = .21

Substitute this value into an equation:

4x + 2 (.21) = .74

4x + .42 = .74

4x = .32

x = .08

So a pencil is worth $.08 and a pen is worth $.21

Added together:

.08 + .21 = $.29

So .29 is your answer

Hope this helps!!!

Let x = the cost of a pencil and y = the cost of a pen.

4x + 2y = $0.74

6x + 5y = $1.53

If you solve the first equation for y, you get

2y = $0.74 - 4x

y = $0.37 - 2x

Now substitute that into the second equation and you get

6x +5($0.37 - 2x) = $1.53

6x + $1.85 -10x = $1.53

$0.32 = 4x

$0.08 = x and y = $0.37 - $0.16 = $0.21

So, a pencil costs $0.08 and a pen costs $0.21. Add those two together to get the cost of a pencil AND a pen.

you make 2 equations form the info.

let x=pencils and y=pens

4x+2y=0.74 and 6x+5y=1.53

now with the two equations, solve for the value of x and y

x=0.08 and y= 0.21
