5=5x
Consider the first equation. Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
5x=5
Swap sides so that all variable terms are on the left hand side.
x=\frac{5}{5}
Divide both sides by 5.
x=1
Divide 5 by 5 to get 1.
x=1 y=-2 z=-2
The system is now solved.
