All right. So you were gonna be given a system that is also multiples of each other t six, and then we have 50 times. This equation is gonna be three x do I 50 z equals 300 then were given 1/2 of the first equation. So point of three acts by this point, there are two y plus 1/2 Z equals three. So again, you should pretty quickly recognizes they're gonna be infinitely many solutions. Since all of these equations air just the same equation, manipulated a little bit, multiplied by different number to sell for one equation, you just plug in zero for Axl, I Z is gonna equal 6006 is an example.
