I need the step by step explanation please send​

Answer 1

Solution →

$\frac{ \frac{3}{4}y + 7 }{ \frac{2}{5}y - 4 } = \frac{5}{4}$

$\frac{ \frac{3y + 28}{4} }{ \frac{2y - 20}{5} } = \frac{5}{4}$

$\frac{5(3y + 28)}{4(2y - 20)} = \frac{5}{4}$

$\frac{3y + 28}{2y - 30} = \frac{5}{4} \times \frac{4}{5}$

$\frac{3y + 28}{2y - 30} = 1$

$3y + 28 = 2y - 30$

$3y - 2y = - 30 - 28$

$y = - 58$
