Answer:

\frac{x+2}{2}-\frac{2x}{5}=5

Step-by-step explanation:

Let x be the smaller even number,

⇒ The larger even number which is consecutive to x = x - 2,

Since, the difference of one half the larger and two fifths the smaller is equal to five.

\implies \frac{1}{2}\times (x+2) - \frac{2}{5}\times x = 5

\implies \frac{x+2}{2}-\frac{2x}{5}=5

Which is the required equation that could be used to determine the number.

w = 2x = 2( \frac{y}{3}) \\ v = 2w = 2 \times 2( \frac{y}{3} ) \\ v + w  + x + y = 180 \\  \frac{4}{3} y +  \frac{2}{3} y +  \frac{y}{3}  + y = 180 \\ y( \frac{4}{3}  +  \frac{2}{3}  +  \frac{1}{3}  + 1) = 180 \\ y =  \frac{180}{()}
