$\frac{5}{6}$ x + 2 = $\frac{7}{8}$

Multiply through by 24 ( the LCM of 6 and 8 ) to clear the fractions

20x + 48 = 21 ( subtract 48 from both sides )

20x = - 27 ( divide both sides by 20 )

x = - $\frac{27}{20}$

Graham is hiking at an altitude of 14,040 feet and is descending 50 feet each minute. Max is hiking at an altitude of 12,500 fee

alina1380 [7]

Graham: -50x + 14,040

Max: 20x + 12,500

Graham = Max

-50x + 14,040 = 20x + 12,500

<u>+50x </u> <u>+50x </u>

14,040 = 70x + 12,500

<u> -12,500 </u> <u> -12.500 </u>

1,540 = 70x

$\frac{1,540}{70} = \frac{70x}{70}$
