Question

0.4z-3/1.5+9=7/5 solve and simplify the following

Answer 1

$\tt \green{hello \: friend \: here \: i s \: your \: anwer : } \\ \ \frac{0.4z - 3}{1.5 + 9} = \frac{7}{5} \\ (0.4z - 3)5 = 7(1.5 + 9) \\ 0.20z - 15 = 10.5 + 63 \\ 0.20z - 15 = 73.5 \\ 0.20z = 73.5 + 15 \\ 0.20z = 88.5 \\ z = \frac{88.5}{0.20}$
