y-5y=0
Consider the second equation. Subtract 5y from both sides.
-4y=0
Combine y and -5y to get -4y.
y=0
Divide both sides by -4. Zero divided by any non-zero number gives zero.
5x-3\times 0=20
Consider the first equation. Insert the known values of variables into the equation.
5x+0=20
Multiply -3 and 0 to get 0.
5x=20
Anything plus zero gives itself.
x=\frac{20}{5}
Divide both sides by 5.
x=4
Divide 20 by 5 to get 4.
x=4 y=0
The system is now solved.
