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 Ron

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:

$(2x+500)+x+(650+2x+500)$

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:

$5x+1,650=2000$

$5x=350$

$x=70$

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.
