Question

que resultado da 2x+y=5 3x-y=5

Answer 1

$2x + y = 5 \\ 3x - y = 5 \\ .................. \\ 2x + y = 5 \\ 2x = 5 - y \\ x = \frac{5 - y}{2} \\ .................. \\ 3x - y = 5 \\ 3( \frac{5 - y}{2} ) - y = 5 \\ \frac{15 - 3y}{2} - y = 5 \\ \frac{15 - 3y - 2y}{2} = 5 \\ 15 - 5y = 10 \\ 5 = 5y \\ y = 1 \\ x = \frac{5 - 1}{2} \\ x = \frac{4}{2} \\ x = 2$
