y=5\times 7^{2}
Consider the second equation. Insert the known values of variables into the equation.
y=5\times 49
Calculate 7 to the power of 2 and get 49.
y=245
Multiply 5 and 49 to get 245.
z=245
Consider the third equation. Insert the known values of variables into the equation.
x=7 y=245 z=245
The system is now solved.
