10\times 5=7x
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 10x, the least common multiple of x,10.
50=7x
Multiply 10 and 5 to get 50.
7x=50
Swap sides so that all variable terms are on the left hand side.
x=\frac{50}{7}
Divide both sides by 7.
x=\frac{50}{7} y=6 z=6
The system is now solved.
