Solve the following systems:

Question

2x + 2z =2
4x + 2y =3
2× + 2y + 2z =1

Answer 1

x+z = 1 so z = (1-x)

2 x + 1 y = 1.5 so y = (1.5 - 2x)

x + y + z = 0.5
so
x + (1.5-2x) + (1-x) = 0.5

x + 1.5 - 2x +1 - x = 0.5

-2 x + 2.5 = 0.5

2 x = 2

x = 1
etc

Answer 2

This was actually just like the last one. It is your turn to do them now. I already passed the course.
