0.05z+0.2-0.15z=-10.5
Subtract 0.15z from both sides.
-0.1z+0.2=-10.5
Combine 0.05z and -0.15z to get -0.1z.
-0.1z=-10.5-0.2
Subtract 0.2 from both sides.
-0.1z=-10.7
Subtract 0.2 from -10.5 to get -10.7.
z=\frac{-10.7}{-0.1}
Divide both sides by -0.1.
z=\frac{-107}{-1}
Expand \frac{-10.7}{-0.1} by multiplying both numerator and the denominator by 10.
z=107
Fraction \frac{-107}{-1} can be simplified to 107 by removing the negative sign from both the numerator and the denominator.
