-473/144=-5/9x-3 7/8<br><br>help

Vlad1618 [11]

Hi,

Work:

$- \frac{473}{144} = - \frac{5}{9}x - 3 \frac{7}{8} \\ - \frac{473}{144} = - \frac{5}{9} x - \frac{21}{8}$

Multiply both sides by 144.

$- 473 - 80x - 378$

Move X to left side and change its side.

$80x = - 378 + 473$

Calculate the sum

$80x = 95$

Divide both sides by 80.

$x = \frac{19}{16}$

Fraction form:

$x = 1 \frac{3}{16}$

Or decimal form:

$1.1875$

Hope this helps.
