y=0.5\times 7+10
Consider the second equation. Insert the known values of variables into the equation.
y=3.5+10
Multiply 0.5 and 7 to get 3.5.
y=13.5
Add 3.5 and 10 to get 13.5.
z=13.5
Consider the third equation. Insert the known values of variables into the equation.
x=7 y=13.5 z=13.5
The system is now solved.
