Макгиди пожалуйста сделать уравнение
7x + 21 = 100 - 16
7x = 100 - 16 - 21
7x = 63
x = 9
____________
x : 121 - 1265 = 3647
x : 121 = 3647 + 1265
x : 121 = 4912
x = 4912 * 121
x = 594352
_____________
787x - 7286 = 20259
x = (20259 + 7286) : 787
x = 27545 : 787
x = 35
120 + 3x = 375
x = (375 - 120) : 3
x = 255 : 3
x = 85
24000 : (x - 12) = 80
x = (24000 : 80) + 12
x = 300 + 12
x = 312
x : 26 + 1654 = 2610
x = (2610 - 1654) * 26
x = 956 * 26
x = 24856
