90=89x
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.
89x=90
Swap sides so that all variable terms are on the left hand side.
x=\frac{90}{89}
Divide both sides by 89.
x=\frac{90}{89} y=5 z=5
The system is now solved.
