Question

a) 2.(x - 6) + 9 = 11
b) 3. Vx + 7 = 13
c) (4x - 2): 2 = x + 7​

Answer 1

a)Solución:

$x = 3 + \sqrt{10} \: 0 \: x = 3 - \sqrt{10}$

b) Solución:

$v = \frac{2}{ {x}^{2} }$

c)solucion:

$x = \frac{15}{16} + \frac{1}{16} \sqrt{249} \: \: 0 \: x = \frac{5}{16} + \frac{ - 1}{16} \sqrt{249}$
