5x=7-20
Consider the first equation. Subtract 20 from both sides.
5x=-13
Subtract 20 from 7 to get -13.
x=-\frac{13}{5}
Divide both sides by 5.
y=-\frac{13}{5}
Consider the second equation. Insert the known values of variables into the equation.
z=-\frac{13}{5}
Consider the third equation. Insert the known values of variables into the equation.
x=-\frac{13}{5} y=-\frac{13}{5} z=-\frac{13}{5}
The system is now solved.
