Kelly has 4 times as many songs on her music player as lou. tiffany has 6 times as many songs on her music player as lou. altogether, they have 682 songs on their music players. how many songs does kelly have?

Let

x---------> the number of songs that Lou has

y---------> the number of songs that Kelly has

z---------> the number of songs that Tiffany has

we know that

---------> equation

---------> equation

---------> equation

Substitute equation and equation in equation

Find the value of y

therefore

the answer is

Kelly has

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
