1-10x=5x+10

4x^2+7=7+24x

7+5 (-9x+7) = - 3

-5x-2+4 (x+1) = 4 (-3-x) - 1

1) - 10 х-5 х=10-1

-15 х=9

х=9: (-15)

х=-0,6

2) 4 х²+7-7-24 х=0

4 х²-24 х=0

4 х (1-6 х) = 0

4 х=0 или 1-6 х=0

х=0 - 6 х=-1

х = 1/6

Ответ: 0; 1/6

3) 7-45 х+35=-3

-45 х=-3-35-7

-45 х=-45

х=1

4) - 5 х-2+4 х+4=-12-4 х-1

-5 х+4 х+4 х=-12-1-4+2

3 х=-15

х=-15/3

х=-5
