Question

resultado d x + 5y÷ 2 + 4y - 3y ÷5​

Answer 1

Respuesta:

d x + 5y÷ 2 + 4y - 3y ÷5​

$dx+5\cdot \frac{y}{2}+4y-3\cdot \frac{y}{5}\\\\=dx+\frac{5y}{2}+4y-3\cdot \frac{y}{5}\\\\=dx+\frac{5y}{2}+4y-\frac{3y}{5}\\\\=\frac{y\cdot \:5}{2}-\frac{y\cdot \:3}{5}+\frac{4y}{1}\\\\=\frac{25y}{10}-\frac{6y}{10}+\frac{40y}{10}\\\\=\frac{25y-6y+40y}{10}\\\\=dx+\frac{59y}{10}$
