35.6. 1) 7x - (x - 2) = 13 – xP(x - 6); 2) 10+ (3 - x)3 = x²(9 - x) -17; 3) -16 + (4 + x)3 = x+(x + 12); 4) 11 - x²(x + 9) = 8x - (x + 3).​

1) 7x-(x-2)^3=13-x^2(x-6)

7х-(x^3-3*2*x^2+3*x*2^2-2^3)=13-x^3+6x^2

7x-x^3+6x^2-12x+8-13+x^3-6x^2=0

-5x-5=0

-5x=5

x=5/-5

x=-1

2) 10+(3- x)^3=x^2*(9-x)-17

10+27 - 27х+9х² - х³ = 9х² - х³ - 17

27х = 54

х = 2

3)-16+64+3*16*x+3*4*x²+x³=x³+12x²

48+48x+12x²+x³-x³-12x²=0

48x+48=0

48x=-48

x=-1

4)11-x^2*(x+9)=8x- (x+3)^3

11 - х³- 9х² = 8х - х³ - 9х² - 27х - 27

-19х = 38

х = -2
