x = 12

Step-by-step explanation:

$\because BD \perp AC... (given) \\\\\therefore m\angle DBA =90\degree... (1)\\\\\because m\angle DBA=(7x + 6)\degree... (2)\\$

From equations (1) & (2)

$(7x + 6)\degree= 90\degree \\\\7x + 6 =90\\\\7x = 90 - 6\\\\7x = 84\\\\x = \frac{84}{7}\\\\\huge \orange {\boxed {x = 12}}$

Mathematics

You can apply a bhaskara formula or the sum and product method. But I would not advise you to do that. Because all the bi-square equations that are without the coefficients c and b at the same time, the solution will always be X = 0

Look:

Y = 4x^2

4x^2 = 0

x^2 = 0 ÷ 4

x^2 = 0

What the value of x ?

Just could be x = 0
