Question

Find the value of x. 10 135-

Answer 1

Step-by-step explanation:

$\frac{x}{12} = \frac{x + 4}{5 + 12}$

$\frac{x}{12} = \frac{x + 4}{17}$

Now cross multiply...

$12(x + 4) = 17x$

$12x + 48 = 17x$

$12x - 17x = - 48$

$- 5x = - 48$

Now divide both term by same number

$\frac{ - 5x}{ - 5} = \frac{ - 48}{ - 5}$

$x = 9.6$
