Question

1/3x +1/4x +1/8x=34/45

Answer 1

1/3x +1/4x +1/8x=34/45

8/24x + 6/24x + 3/24x = 34/45

17/24x = 34/45

x = 34/45 * 24/17

x = 48/45

x = 1 3/45 = 1 1/15

Answer 2

$frac{1}{3x}+frac{1}{4x}+frac{1}{8x}=frac{34}{35}\\frac{8}{24}+frac{6}{24}+frac{3}{24x}=frac{34}{35} \\frac{17}{24x}=frac{34}{35} \\x=frac{34}{35}*frac{24}{17} \\x=frac{816}{765} =frac{16}{15}=1frac{1}{15}$
