Question

Por favor me ajudem 4x+2y=6 2x+5y=-4

Answer 1

4x + 2y = 6

2x + 5y = -4

4x + 2y = 6

2y = 6 - 4x

$y = \frac{6 - 4x}{2}$

$2x +5( \frac{6-4x}{2}) = -4\\ \\ \frac{2x + 30 -20x = -4}{2} \\ \\ \frac{4x + 30 - 20x = -8}{2}\\ \\  4x+30-20x=-8\\ 4x-20x=-8-30\\ -16x =-24\\ x = -24 / -16 x = -12/8 = -6/4 = \\ x = -3/2$

$4 - \frac{3}{2} + 2y = 6\\ \\ \frac{8 - 3 + 4y = 12}{2} \\\\  8-3+4y = 12\\ 4y = 12 +3 - 8 \\ 4y = 15-8\\  y = 7/4$

x = -3/2

y = 7/4
