Question

solve:o.4Ζ-3/1.5Ζ+9=7/5

Answer 1

HEY HERE IS YOUR ANSWER☺☺☺

$4z - \frac{3}{1.5z} + 9 = \frac{7}{5} \\ \\ 4 z - \frac{30}{15z} + 9 = \frac{7}{5} \\ \\ 4z - \frac{2}{z} = \frac{7}{5} - 9 \\ \\ 4z - \frac{2}{z} = \frac{7 - 45}{9} \\ \\ 4z - \frac{2}{z } = \frac{-38}{9} \\ \\ 4z - 2 = \frac{-38}{9} \times z \\ \\ 4z - 2 = \frac{-38z}{9} \\ \\ - 2 = \frac{-38z}{9} - 4z \\ \\ - 2 = \frac{-38z - 36z}{9} \\ \\ - 2 = \frac{-74z}{9} \\ \\ \frac{ - 9\times 2}{74} =-z \\ \\ -9/37 = -z$
9/37 = z
