Question

Solve 3x-6y+5z=2 when x=2 and z = -2

Answer 1

Plug 2 in where x is and -2 for z and solve for y

Answer 2

So substitute the values of x and z and solve for the remaining y..

Answer 3

3(2)-6y+5(-2)=2

Answer 4

The reason I ask this is because in the system
3x-6y+5z=2
3x+3y-z=5
5x+6y+5z=-6

When I try to plug in the values and solve for y, I get a strange answer... but when I plug it into the other equations, I get the correct answer. Why is this?

Answer 5

I don't understand -6y = 8??

Answer 6

WAIT
