Question

he difference of two numbers is 50. twice one number equals three times the other. find the numbers.

Answer 1

x-y=50 and 2x=3y 
x=y+50 so 2(y+50) = 3y 

2y+100=3y
y=100

x-100=50
x=150

so our numbers are 150 and 100 

150-100=50 and 150 is 3*50 and 100 is 2*50 so fits all requirements!

hope this helps you! thank you!
