1.61z-3.4-1.4z=-4.61
Subtract 1.4z from both sides.
0.21z-3.4=-4.61
Combine 1.61z and -1.4z to get 0.21z.
0.21z=-4.61+3.4
Add 3.4 to both sides.
0.21z=-1.21
Add -4.61 and 3.4 to get -1.21.
z=\frac{-1.21}{0.21}
Divide both sides by 0.21.
z=\frac{-121}{21}
Expand \frac{-1.21}{0.21} by multiplying both numerator and the denominator by 100.
z=-\frac{121}{21}
Fraction \frac{-121}{21} can be rewritten as -\frac{121}{21} by extracting the negative sign.
