Question

how to check x/2-1/5=x/3+1/4​

Answer 1

Answer:

$\frac{x}{2} - \frac{1}{5} = \frac{x}{3} - \frac{1}{4} \\ \\ = \frac{5x - 2}{10} = \frac{4x - 3}{12} \\ \\ = 12(5x - 2) = 10(4x - 3) \\ \\ = 60x - 24 = 40x = 30 \\ \\ 60x - 40x = 30 + 24 \\ \\ 20x = 54 \\ \\ x = \frac{54}{20} \\ \\ x = \frac{27}{10} \\ \\ x = 2.7$
