Solve for t
t=-\left(x+2z\right)
Solve for x
x=-\left(2z+t\right)

-t=x+2z
Swap sides so that all variable terms are on the left hand side.
\frac{-t}{-1}=\frac{x+2z}{-1}
Divide both sides by -1.
t=\frac{x+2z}{-1}
Dividing by -1 undoes the multiplication by -1.
t=-\left(x+2z\right)
Divide x+2z by -1.
x=-t-2z
Subtract 2z from both sides.
