y=4.5
Consider the second equation. Add 4 and 0.5 to get 4.5.
0=-7s
Consider the third equation. Anything plus zero gives itself.
-7s=0
Swap sides so that all variable terms are on the left hand side.
s=0
Divide both sides by -7. Zero divided by any non-zero number gives zero.
x=5+0\times 0
Consider the first equation. Insert the known values of variables into the equation.
x=5+0
Multiply 0 and 0 to get 0.
x=5
Add 5 and 0 to get 5.
x=5 s=0 y=4.5
The system is now solved.
