2x+3=95 \\
2x=95-3 \\
2x=92 \\

If x / 2y = 0.4 , A / 5B = 0.25 Then A + y / 5 =….... ​
shusha [124]

Answer:

\frac{x}{2y}  =  \frac{4}{10}  \\ 8y = 10x \\ y =  \frac{10x}{8} -  -  -  -  - 1  \\  \\  \frac{a}{5b}  =  \frac{25}{100}  \\  \frac{a}{5b}  =  \frac{1}{4}  \\ 4a = 5b \\ a =  \frac{5b}{4}  -  -  - 2 \\  \\ so \:  \:  \frac{a + y}{5}  \\  = (a + y) \times  \frac{1}{5}  \\  = ( \frac{5b}{4}  +  \frac{5x}{4} ) \times  \frac{1}{5}  \\  =  \frac{5b + 5x}{4}  \times  \frac{1}{5}  \\  =  \frac{5(b + x)}{4}  \times  \frac{1}{5}  \\  =  \frac{b + x}{4}  \\  \\ so \:  \:  \:  \frac{a + y}{5}  =  \frac{b + x}{4}
