Question

5 5/12x-2 3/14=5 1/4x-3 5/7

Answer 1

$5 \frac{5}{12} x - 2 \frac{3}{14} = 5 \frac{1}{4} x - 3 \frac{5}{7} \\ \frac{65}{12} x - 2 \frac{3}{14} = 5 \frac{1}{4} \times x - 3 \frac{5}{7} \\ \frac{65}{12} x - \frac{31}{14} = 5 \frac{1}{4} \times x - 3 \frac{5}{7} \\ \frac{65}{12} x - \frac{31}{4} x = \frac{21}{4} x - 3 \frac{5}{7} \\ \frac{65}{12} x - \frac{31}{14} = \frac{21}{4} x - \frac{26}{7} \\ 455x - 186 = 441x - 312 \\ 455x - 441x = - 312 + 186 \\ 14x = - 312 + 186 \\ 14x = - 126 \\ x = - 9$
