y=4\left(2\times 5-1\right)
Consider the second equation. Insert the known values of variables into the equation.
y=4\left(10-1\right)
Multiply 2 and 5 to get 10.
y=4\times 9
Subtract 1 from 10 to get 9.
y=36
Multiply 4 and 9 to get 36.
z=36
Consider the third equation. Insert the known values of variables into the equation.
x=5 y=36 z=36
The system is now solved.
