How do i solve each proportion?

natali 33 [55]

You have to cross multiply (multiply the numerator of the first by the denominator of the second and the numerator of the second by the denominator of the first).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[19]

$\frac{x+4}{3} = \frac{4}{10}$

$10x+40=12$

$10x = -28$

$x=-2.8$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[21]

$\frac{4}{n+8} = \frac{10}{8}$

$32 = 8n + 64$

$8n = -32$

$n=-4$
