Question

solve the following equation and check the answer2/5z = 3/8z+7/20 please help to find the equation​

Answer 1

Question :-

solve the following equation =>2/5z = 3/8z+7/20

__________________________

Given :-

$\sf \: \frac{2}{5} z = \frac{3}{8}z + \frac{7}{20}$

______________________

we have to find "z"

__________________________

$\mathtt{{\colorbox{purple}{solution}}}</p><p> \\ \sf \: \frac{2}{5} z = \frac{3}{8} z + \frac{7}{20} \\ \sf \: = > \frac{2}{5} z - \frac{3}{8} z = \frac{7}{20} \\ \sf \: = > \frac{ 162 - 152}{40} = \frac{7}{20} \\ = > \sf \: z = \frac{7}{20 \times 40} \\ \sf \: = > z = 14$

__________________________

Hence , 14 is the answer
