Решите уравнение: а) 2x-5(x+2)=-(3x+6) б)-+5)=-2(x+4) в)(x+6)=1 г)x-4/5=1-3x/-2 д)1-x/5 + 2x-4/3=x+3/10 е)(3x+2)*(3x--4)^2=28 ж)(4x+1)*(16x^2-4x+1)-16x(4x^2-5)=17

А) 2x - 5x + 10 = -3x - 6
-3x + 10 = -3x - 6
10 = -6
б) -3x + x - 5 = -2x - 8
-2x -5 = -2x -8
-5 = -8
в) x = 1 - 6
x = -5
г)-2 (x - 4) = 5 (1 - 3x)
-2x + 8 = 5 - 15x
-2x + 15x = 5 - 8
13 = -3
д)6 (1 - x) + 10 (2x - 4) = 3 (x + 3)
6 - 6 x + 20x - 40 = 3x + 9
-34 + 14x = 3x + 9
14x - 3x = 9 + 34
11x = 43
x = 43/11
е)9x^2 - 4 - (9x^2 - 2x + 16) = 28
9x^2 - 4 - 9x^2 + 24x - 16 = 28
-20 + 24x = 28
24x = 28 +200
24x = 48
x = 2
