Help! Clear the fractions
I am Lyosha [343]

Answer:

x = - \frac{27}{20}

Step-by-step explanation:

Given

\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}

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}
