Two boxes with different masses are tied together on a frictionless ramp surface. what is the tension in each of the cords?

When we look at the forces acting on the boxes, all forces acting verticaly are irrelevant.

Horizantal forces acting on the body are T and mgx

However tension cannot be found with the above information included.

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )
