\(x\) — любое число

–12x + 4(x – 3) = – 8x – 12

8(x – 3) + 1 = 5(2x + 3) – 2х

7(x – 4) + 3 = 3(2x – 7) + x – 8

4(x + 2) – 0,7 = 2(2x + 4) + 0,3

5х – 3(4х – 1) = 7 – 2(7х + 2)

–2(x + 21) – 3(x – 14) = –5x

5(3х + 1) + 2х = 4х + 5

2(x + 21) + 3(x – 4) = 5(x + 6)

5(6х – 1) = 3х – 5

1,2x + 0,3(7 – x) = 2,1 + 0,9х

–5,6(x – 3) + 2,1x = –3,5x + 10

6х – 3(5х + 4) – 2(7х – 3) = –6
