Answer: x=0, y=56

Step-by-step explanation:

If both triangles are proportional, plug in the equations.

As you can see, you have two equations to work with.

10x+y=56

3x+6=9

get rid of x as a variable first by multiplication.

30x+3y=168

30x+60=90

3y=168

168/3=56

y=56

Now solve for x.

10x+(56)=56

10x=0

x=0
