Допоможіть будь-ласка
1) 3(x-2)= -10x
2) –3(x-3)=7
3) –(2x–5) = -5x

Answer 1

Ответ:

$1) \\ 3x - 6 = - 10x \\ 3x - 6 = - 10x \\ 3x + 10x = 6 \\ 13x = 6 \\ x = \frac{6}{13 } \\ 2) \\ - 3x + 9 = 7 \\ - 3x = 7 - 9 \\ - 3x = - 2 \\ x = \frac{2}{3} \\ 3) \\ - 2x + 5 = - 5x \\ - 2x + 5x = - 5 \\ 3x = - 5 \\ x = - \frac{5}{3}$
