1. $1 - 5x - 6x + 8 = 9 - 11x$ 2. $2 - 3(2x + 2) = 5 - 4x$ $2 - 6x - 6 = 5 - 4x$ $-6x - 4 = 5 - 4x$ $-2x = 9$ $x = -4,5$ 3. $-9(8 - 9x) = 4x + 5$ $-72 + 81x = 4x + 5$ $77x = 77$ $x = 1$ 4. $(-x + 7)(-8x + 5) = 0$ $-x + 7 = 0 \implies x = 7$ $-8x + 5 = 0 \implies x = 0,625$ 5. $16 + 6x = 5(1 - 2x) - 13$ $16 + 6x = 5 - 10x - 13$ $16 + 6x = -10x - 8$ $16x = -24$ $x = -1,5$ 6. $6(3x + 1) - 3x = 11x$ $18x + 6 - 3x = 11x$ $15x + 6 = 11x$ $4x = -6$ $x = -1,5$ 7. $3(3 - 2x) + 8 + 2x = 5$ $9 - 6x + 8 + 2x = 5$ $-4x + 17 = 5$ $-4x = -12$ $x = 3$ 8. $5 = 12 - 5(4x - 1)$ $5 = 12 - 20x + 5$ $5 = 17 - 20x$ $20x = 12$ $x = 0,6$

2 вариант 1. 1 - 5x + -6x +8 2. 2 - 3(2x+ 2) = 5 - 4x 3. - 9(8 - 9x) = 4x + 5 4. (- x + 7)(-8x + 5) = 0 5. 16 + 6x = 5(1 - 2x) - 13 6. 6(3x + 1) - 3x = 11x 7. 3(3 - 2x) + 8 + 2x = 5 8. 5 = 12 - 5(4x - 1)
