Решение:
- 1) \(4x - 2 = 7x + 10\)
\(4x - 7x = 10 + 2\)
\(-3x = 12\)
\(x = \frac{12}{-3}\)
\(x = -4\) - 2) \(7x - 2(3x + 6) = 8\)
\(7x - 6x - 12 = 8\)
\(x - 12 = 8\)
\(x = 8 + 12\)
\(x = 20\) - 3) \(\frac{7x-3}{2} = \frac{5x-6}{5}\)
\(5(7x-3) = 2(5x-6)\)
\(35x - 15 = 10x - 12\)
\(35x - 10x = 15 - 12\)
\(25x = 3\)
\(x = \frac{3}{25}\)
Ответ: 1) \(x = -4\) 2) \(x = 20\) 3) \(x = \frac{3}{25}\)
