Question

/(x-) +/(x+) =/(x+) +​

Answer 1

Step-by-step explanation:

$\frac{x - 2}{3} + \frac{x + 3}{4} = \frac{x + 4}{5} + 15 \\ \frac{4(x - 2)}{12} + \frac{3(x + 3)}{12} = \frac{x + 4}{5} + 15 \\ \frac{4x - 8 + 3x + 9}{12} = \frac{x + 4}{5} + \frac{15 \times 5}{5} \\ \frac{7x + 1}{12} = \frac{x + 4 + 75}{5} \\ 5(7x + 1) = 12(x + 79) \\ 35x + 5 = 12x + 12 \times 79 \\ 35x - 12x = 12 \times 79 - 5 \\ 13x = 943 \\ x = 72.5$
