t\left(-2\right)+t=-1
Consider the second equation. Add t to both sides.
-t=-1
Combine t\left(-2\right) and t to get -t.
t=\frac{-1}{-1}
Divide both sides by -1.
t=1
Divide -1 by -1 to get 1.
1\left(-2\right)=1+r\left(-1\right)
Consider the first equation. Insert the known values of variables into the equation.
-2=1+r\left(-1\right)
Multiply 1 and -2 to get -2.
1+r\left(-1\right)=-2
Swap sides so that all variable terms are on the left hand side.
r\left(-1\right)=-2-1
Subtract 1 from both sides.
r\left(-1\right)=-3
Subtract 1 from -2 to get -3.
r=\frac{-3}{-1}
Divide both sides by -1.
r=3
Fraction \frac{-3}{-1} can be simplified to 3 by removing the negative sign from both the numerator and the denominator.
t=1 r=3
The system is now solved.
