Question

2x2+2y=14 sistema de ecuacion
​

Answer 1

2x2+2y=14

operaciones:

$2x ^ 2 + 2y-14 = 0\\\\(2) * x ^ 2 + (2y-14) = 0\\\\x = (+ - raiz cuadrada (- (2) * (2y-14))) / (2)\\\\x = (+ - raiz cuadrada (-4y + 28)) / (2)\\\\x = (+ - (2) * sqrt (-y + 7)) / (2)\\\\x = + - (\ cancelar {(2)} * sqrt (-y + 7)) / (\ cancelar {(2)})\\\\x_1 = raiz cuadrada (-y + 7)\\\\x_2 = -sqrt (-y + 7)$

resultado final:

⇒  $-sqrt (-y + 7)$
