Question

$x3 + 3x \div 3x2 + 1 = 234 \div 109 \: then \: x + 5 = what$
​

Answer 1

Answer:

11

Step-by-step explanation:

From the given equation, on comparison we can have

$3x^{2} +1 = 109\\\\Therefore, 3x^{2} = 109 - 1 = 108\\\\So, x^{2} = 108/3 = 36\\So, x = 6$

This value of x also satisfy x3 + 3x = 234

Therefore, x + 5 = 6 + 5 = 11

Thanks.
