Question

valor de "X" 6x+2y=46 4x-5y=-1

Answer 1

Explicación paso a paso:

$6x + 2y = 46 \\ 6x = 46 - 2y \\ x = \frac{46 - 2y}{6} \\ 4x - 5y = - 1 \\ 4x = - 1 + 5y \\ x = \frac{ - 1 + 5y}{4} \\ \frac{46 - 2y}{6} = \frac{ - 1 + 5y}{4} \\ 184 - 8y = - 6 + 30y \\ 184 + 6 = 30y + 8y \\ 190 = 38y \\ y = \frac{190}{38} = 5$

$6x + 2y = 46 \\ 6x + 2 \times 5 = 46 \\ 6x + 10 = 46 \\ 6x = 46 - 10 \\ 6x = 36 \\ x = \frac{36}{6} = 6 \\ 6 \times 6 + 2 \times 5 = 36 + 10 = 46 \\ 4 \times 6 - 5 \times 5= 24 - 25 = - 1$
