Question

igualacion e)
13x + 8y = 2
11x + 4y = 1​

Answer 1

Explicación paso a paso:

$11x + 4y = 1 \\ 2(11x + 4y) = 2 \times 1 \\ 22x + 8y = 2$

$13x + 8y = 2 \\ 22x + 8y = 2$

Se resta ambas ecuaciones

$22x - 13x + 8y - 8y = 2 - 2 \\ 9y = 0 \\ y = 0$

$11x + 4y = 1 \\ 11x + 4 \times 0 = 1 \\ 11x + 0 = 1 \\ 11x = 1 \\ x = \frac{1}{11}$
