Let the amount the friend pays be x. Then, 2 times what the friend pays is 2x. Less $2,000 what the friend pays is 2x-2000.
Now we know that
2x-2000=48000
Add 2000 to both sides of the equation
2x-2000+2000=48000+2000
2x+2000-2000=50000
2x=50000
Divide both sides by 2
X=25000
Thus, the friend pays $25,000 for their car.
