Question

$\left \{ {{4x+1=3y} \atop {2x-3=2y}} \right.$ Como resolvo isso?

Answer 1

$4x + 1 = 3y \\ 2x - 3 = 2y \: \: \: ( \times - 2) \\ \\ 4x + 1 = 3y \\ - 4x + 6 = - 4y \\ \\ 7 = - y \\ - y = 7 \: \: \: \: ( \times - 1)\\ y = - 7 \\ \\ 4x + 1 = 3( - 7) \\ 4x + 1 = - 21 \\ 4x = - 22 \\ x = \frac{ - 22}{4} \\ x = \frac{ - 11}{2}$

Resposta final: x = -11/2 , y= -7
