3x=2-7
Consider the first equation. Subtract 7 from both sides.
3x=-5
Subtract 7 from 2 to get -5.
x=-\frac{5}{3}
Divide both sides by 3.
y=5+3\left(-\frac{5}{3}\right)
Consider the second equation. Insert the known values of variables into the equation.
y=5-5
Multiply 3 and -\frac{5}{3} to get -5.
y=0
Subtract 5 from 5 to get 0.
z=0
Consider the third equation. Insert the known values of variables into the equation.
x=-\frac{5}{3} y=0 z=0
The system is now solved.
