Question

f)
(2x + 3y = 1
3x + 2y = 4​

Answer 1

Explicación paso a paso:

$2x + 3y = 1 \\ 2x = 1 - 3y \\ x = \frac{1 - 3y}{2}$

$3x + 2y = 4 \\ 3x = 4 - 2y \\ x = \frac{4 - 2y}{3}$

$\frac{1 - 3y}{2} = \frac{4 - 2y}{3} \\ 3 - 9y = 8 - 4y \\ - 8 + 3 = - 4y + 9y \\ - 5 = 5y \\ y = \frac{ - 5}{5} = - 1$

$x = \frac{4 - 2y}{3} = \frac{4 - 2 \times ( - 1)}{3} = \frac{4 + 2}{3} = \frac{6}{3} = 2$

2*2+3*(-1)=1

3*2+2*(-1)=4
