Question

me ayudan a resolver esto <3 para ahoritta :

Answer 1

Explicación paso a paso:

$8x - 2y = - 4 \\ 4x + 3y = 18 \: \: ( \times - 2) \\ - 8x - 6y = - 36 \\ 8x - 2y = - 4 \\ - 8y = - 40 \\ 8y = 40 \\ y = \frac{40}{8} = 5$

$4x + 3y = 18 \\ 4x + 3 \times 5 = 18 \\ 4x + 15 = 18 \\ 4x = 18 - 15 \\ 4x = 3 \\ x = \frac{3}{4}$

$8 \times \frac{3}{4} - 2 \times 5 = \frac{24}{4} - 10 = 6 - 10 = - 4$

$4 \times \frac{3}{4} + 3 \times 5 = \frac{12}{4} + 15 = \\ 3 + 15 = 18$

$32xy = 32 \times ( \frac{3}{4} \times 5) = 32 \times \frac{15}{4} = \frac{480}{4} = 120$

espero te sirva
