the difference between two numbers is 4. three times the smaller number minus four times the larger is -28.. what are the numbers?

OpenStudy (anonymous):

x = 16 y = 12

OpenStudy (anonymous):

9a squared - 121

OpenStudy (anonymous):

x - first number, y - second number \[\begin{cases}x-y=4\\3y-4x=-28\end{cases}\] I hope you can do it yourself now x=16 y=12

OpenStudy (aroub):

The first number: x ==> smaller number The second number: x+4 ==> larger number =>3(x)-4(x+4)=-28 =>3x-4x-16=-28 =>3x-4x=16-28 =>-x=12 =>x=12 The number are: 12,16 :D
