x\times 75=300
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 300x, the least common multiple of 300,x.
x=\frac{300}{75}
Divide both sides by 75.
x=4
Divide 300 by 75 to get 4.
y=4
Consider the second equation. Insert the known values of variables into the equation.
z=4
Consider the third equation. Insert the known values of variables into the equation.
x=4 y=4 z=4
The system is now solved.
