Un sofá y un asiento de amor juntos cuesta $ 444. El sofá cuesta el doble del asiento del amor. ¿Cuánto cuestan cada uno?

Let cost of sofa=x

and cost of love seat=y

x+y=444

x=2y

2y+y=444

3y=444

y=444/3

y=148

x=2y= 2*148= 296

Cost of sofa=$296

Cost of love seat=$148

Hope it helps:-)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
