Question

2x mas 2 sobre 2 igual a 45x menos 30 sobre 5​

Answer 1

Explicación paso a paso:

$2x + \frac{2}{2} = 45x - \frac{30}{5} \\ \\ 2x + 1 = 45x - 6 \\ 2x - 45x = - 6 - 1 \\ - 43x = - 7 \\ x = \frac{7}{43} \\ comprobación \\ 2 \times \frac{7}{43} + \frac{2}{2} = 45 \times \frac{7}{43} - \frac{30}{5} \\ \\ \frac{14}{43} + 1 = \frac{315}{43} - 6 \\ \\ \frac{14 + 43}{43} = \frac{315 - 258}{43} \\ \\ \frac{57}{43} = \frac{57}{43}$
