Question

2x+3y=8
-3x+y=-1
con sistema de reducción y paso a paso porfa

Answer 1

Respuesta:

$2x + 3y = 8 \\ - 3x + y = - 1 \\ \\ 3(2x) + 3(3y) = 3(8) \\ 2(- 3x) + 2(y) = 2( - 1 ) \\ \\ 6x + 9y = 24 \\ - 6x + 2y = - 2 \\ \\(6x )+ 9y = 24 \\ (- 6x) + 2y = - 2 \\ \\ 9y = 24 \\ 2y = - 2 \\ \\ 11y = 22 \\ y = \frac{22}{11} \\ y = 2$

$2x + 3(2) = 8 \\ 2x + 6 = 8 \\ 2x = 8 - 6 \\ x = \frac{2}{2} \\ x = 1$
