3.5X+6.8Y=69
X+Y15
Y=15-X
3.5X+6.8(15-X)=69
3.5X-6.8X+102=69
-3.3X=69-102
-3.3X=-33
X=10
When X=10
X+Y=15
10+Y=15
Y=15-10
Y=5
X=10, Y=5

Is there a way to do this challenging math problem without algebra? If so, can you possibly answer it in this such way

Unfortunately no. That is the only way unless you were just going to throw random numbers at it to see what combination works. That is how I figured it out before even doing the algebra to solve it.
