Question

Математика: 350 : (20 x X - 15) = 70420 + (4 x X + 360) = 940350 + (600 - 5 x X) = 450 ​

Bagdan112 · Answer

Первое не знаю420 + (4 X + 360) = 9404 X + 360 = 940 - 4204 X + 360 = 5204 X = 520 - 3604 X = 160X = 40350 + (600 - 5 X) = 450600 - 5 X = 450 - 350600 - 5 X = 1005 X = 600 - 1005 X = 500X = 100...

350 : (20 x X - 15) = 70420 + (4 x X + 360) = 940350 + (600 - 5 x X) = 450 ​

350 : (20 x X - 15) = 70
420 + (4 x X + 360) = 940
350 + (600 - 5 x X) = 450
