Как решить уравнение?
124-24*(480:x-56)=28

124 - 24*(480:х-56)= 28
24*(480:х-56) = 124 - 28
24*(480:х-56)= 96
480:х -56 = 96:24
480 : х - 56 = 4
480 : х = 56 + 4
480:х = 60
Х = 480:60
Х = 8
--------------
124 - 24(480:8 - 56) = 28
124 - 24(60-56) = 28
124 - 24*4 = 28
124 - 96 = 28
28 = 28

[tex]124 - 24.(480 : x - 56) = 28 \\\ 124 - 24.(\frac{480}{x} - 56) = 28 \\\\ 124 - 24.\frac{480}{x} - (-24.56) = 28 \\\\ 124 - \frac{11520}{x} + 1344 = 28 \\\\ - \frac{11520}{x} + 1468 = 28 \\\\ - \frac{11520}{x} = 28 - 1468 \\\\ - \frac{11520}{x} = - 1440 \\\\ \frac{11520}{x} = 1440 \\\\ 1440x = 11520 \\\ x = \frac{11520}{1440} \\\\ x = 8[/tex]

I hope I have helped. Have a good day!!
