Question

Solve the following system of equations for all three variables.

5x + 7y + 2z = -7
9x + 7y + 2z = 5
2x - 7y5z = -2
X=
y =
z =

Answer 1

X= -7/5 - 7y/5 - 2z/5

X= 5/9 - 7y/9 - 2z/9

X= -1 + 7y^5z/2

Y= -1 - 5x/7 - 2z/7

Y= 5/7 - 9x/7 - 2z/7

Y= (square root symbol is the line--->) ^5 |4802z^4(x+1)/7z

Z= -7/2 - 5x/2 - 7y/2

Z= 5/2 - 9x/2 - 7y/2

Z= 2/7y^5 + 2x/7y^5

Explanation:

I hope this makes sense.
