Answer 1

6(8+x)-10=-9
48+6х-10=-9
38+9=-6х
47=-6х

Answer 2

1) 6(8+x) - 10 = -9 48 + 6x - 10 = -9 6x + 38 = -9 6x = -9 - 38 6x = -47 x = -47 / 6

2) -5(-1-3x) - 5x = -1 5 + 15x - 5x = -1 10x + 5 = -1 10x = -1 - 5 10x = -6 x = -6 / 10 x = -3 / 5

3) 4(-6-9x) - x = 5 -24 - 36x - x = 5 -37x - 24 = 5 -37x = 5 + 24 -37x = 29 x = 29 / -37

4) -7(9+x) - 8x = -2 -63 - 7x - 8x = -2 -15x - 63 = -2 -15x = -2 + 63 -15x = 61 x = 61 / -15

5) -9x + 7(-10+3x) = -8x - 2 -9x - 70 + 21x = -8x - 2 12x - 70 = -8x - 2 12x + 8x = -2 + 70 20x = 68 x = 68 / 20 x = 17 / 5

6) x - 9 + (-8 + x) = -10x + 9 x - 9 - 8 + x = -10x + 9 2x - 17 = -10x + 9 2x + 10x = 9 + 17 12x = 26 x = 26 / 12 x = 13 / 6

7) 2x + 2(5+7x) = 9x + 4 2x + 10 + 14x = 9x + 4 16x + 10 = 9x + 4 16x - 9x = 4 - 10 7x = -6 x = -6 / 7

8) 5x - 10(1+3x) = 2x - 6 5x - 10 - 30x = 2x - 6 5x - 30x - 2x = -6 + 10 -27x = 4 x = 4 / -27 x = -4 / 27
