Question

как решить уровнение 2,4:(x+0,98)=4,08

Answer 1

2,4:(x+0,98)=4,08
$x + 0,98 = 2,4 : 4,08 \\ \\ x+0,98= \frac{240}{408} \\ \\ x+0,98= \frac{30}{51} \\ \\ x= \frac{30}{51} -0,98 \\ \\ x = \frac{30}{51} - \frac{98}{100} \\ \\ x = \frac{30}{51} - \frac{49}{50} \\ \\ x= \frac{30*50-49*51}{51*50} \\ \\ x= \frac{1500-2499}{2550} \\ \\ x=- \frac{999}{2550} \\ \\ x=- \frac{333}{850}$
