Mark ronnie and lisa bought a 75 inch curved 4000 television. lisa put 650 more than mark had. mark had twice as much and then ronnie plus $500 the total cost of the television was 2000.how much did everyone give to buy the television? mark 2x+500 ronnie x lisa 650+2x+500

So since you gave all of the equations of everyone's amount that they put in, it saves some work.

Let's add up everyone's contribution and then solve for x:

Then since we know the television costs $2,000, we can set this expression equal to that and simplify terms. Then we can solve for x:

So since Ronnie put in 'x', we can say that Ronnie paid $70.

Since Mark put in '2x + 500', we can plug in 70 for x to find that Mark paid $640.

And since Lisa put in '650 + 2x + 500', we can plug in 70 for x again to find that Lisa paid $1,290.

answer: 15
