  • Группы
    • решений нет
    • \(x\) — любое число
    • \(x=0\)
  • Варианты
    • 8\(x – 3\) + 1 = 5\(2x \+ 3\) – 2х
    • 6х – 3\(5х \+ 4\) – 2\(7х – 3\) = –6
    • –2\(x \+ 21\) – 3\(x – 14\) = –5x
    • 7\(x – 4\) + 3 = 3\(2x – 7\) + x – 8
    • 5\(6х – 1\) = 3х – 5
    • 5х – 3\(4х – 1\) = 7 – 2\(7х \+ 2\)
    • 5\(3х \+ 1\) + 2х = 4х + 5
    • 4\(x \+ 2\) – 0,7 = 2\(2x \+ 4\) + 0,3
    • 1,2x + 0,3\(7 – x\) = 2,1 + 0,9х
    • 2\(x \+ 21\) + 3\(x – 4\) = 5\(x \+ 6\)
    • –5,6\(x – 3\) + 2,1x = –3,5x + 10
    • –12x + 4\(x – 3\) = – 8x – 12
