Question

Как решить? (x+9 7/8)-4 1/2=7 3/4​

Answer 1

Ответ:

x=2,375

x+9 7/8 - 4 1/2 = 7 3/4

x+43/8= 7 3/4

x=7 3/4 - 43/8

x=19/8

Answer 2

Ответ:

$x + 9 \frac{7}{8} - 4 \frac{1}{2} = 7 \frac{3}{4} \\ x + 5 \frac{7 - 4}{8} = 7 \frac{3}{4} \\ x + 5 \frac{3}{8} = 7 \frac{3}{4} \\ x = 7 \frac{3}{4} - 5 \frac{3}{8} \\ x = 2 \frac{6 - 3}{8} \\ x = 2 \frac{3}{8}$
