Question

(1 5/8-24/7)*5,4х=9 1/2+ 2 1/4. срочно​

Answer 1

$( 1\frac{5}{8} - \frac{24}{7} ) \times 5.4x = 9 \frac{1}{2} + 2 \frac{1}{4} \\ \\ (1 \frac{5}{8} - 3 \frac{3}{7} ) \times 5.4x = 9.5 + 2.25 \\ \\ ( 1\frac{35}{56} - 3 \frac{24}{56} ) \times 5.4x = 11.75 \\ \\ ( \frac{91}{56} - 1 \frac{136}{56} ) \times 5.4x = 11.75 \\ \\ - 1 \frac{45}{56} \times 5.4x = 11.75 \\ \\ 5.4x = - \frac{1175 \times 56}{100 \times101 } \\ \\ 5.4x = - 6 \frac{52}{101} \\ \\ x = - \frac{10 \times 658}{54 \times 101} \\ \\ x = - 1 \frac{563}{2727}$
