1) -4(x-10) = 12(x-1)-4x + 40 = 12x - 12-4x - 12x = -12 - 40-16x = -52x = -52 / -16x = 13/4
Ответ: x = 13/4
2) a + 5x = b + 2xВыразим x:5x - 2x = b - a3x = b - ax = (b - a) / 3
Ответ: x = (b - a) / 3
1) -4(x-10) = 12(x-1)
-4x + 40 = 12x - 12
-4x - 12x = -12 - 40
-16x = -52
x = -52 / -16
x = 13/4
Ответ: x = 13/4
2) a + 5x = b + 2x
Выразим x:
5x - 2x = b - a
3x = b - a
x = (b - a) / 3
Ответ: x = (b - a) / 3
