Question

ecuaciones 5/2 x + 40 = 500​

Answer 1

Respuesta:

x=184

Explicación paso a paso:

$\frac{5}{2} x + 40 = 500 \\ \\ \frac{40}{1} \times \frac{2}{2} = \frac{80}{2 } \\ \\ \frac{5}{2} x + \frac{80}{2} = 500 \\ \\ \frac{5x + 80}{2} = \frac{1000}{2}$

$5x + 80 = 1000 \\ 5x = 1000 - 80 \\ 5x = 920 \\ x = \frac{920}{5} = 184$

$\frac{5}{2} \times 184 + 40 = 500$
