Question

3x+2y=10 2x-2y=0 método de sustitución ​

Answer 1

Explicación paso a paso:

$2x - 2y = 0 \\ 2x = 2y \\ x = \frac{2y}{2} = y \\ x = y \\ 3x + 2y = 10 \\ 3x + 2x = 10 \\ 5x = 10 \\ x = \frac{10}{5} = 2 \\ x = 2 \\ y = 2$

$3x + 2y = 10 \\ 3 \times 2 + 2 \times 2 = 6 + 4 = 10 \\ 2x - 2y = 2 \times 2 - 2 \times 2 = 4 - 4 = 0$

espero te sirva
