Exercise 1.2.38 Find the solrion to the system of equations, 3r-y-2z=3, y-4z=0, and -2x+y= -2.

Solve the following system of equation (1) x+y+z= 10 (2) y+ 2z = 6 (3) O O Z=0 (4, -6,0) (-4,6,0) (4.6.0)

In each part, solve the linear system, if possible, and use the result to determine whether the lines represented by the equa- tions in the system have zero, one, or infinitely many points of intersection. If there is a single point of intersection, give its coordinates, and if there are infinitely many, find parametric equations for them 3x−2y=4 6x − 4y = 9
