прмогите кто разбирается решить уравнкния​

Answer 1

Ответ и пошаговое объяснение:

$1)\ 4(x-8) = -5\\4x - 32 = -5\\4x = -5 + 32\\4x = 27\\x = \dfrac{27}{4} = 6\dfrac{3}{4} = 6,75;\\\\2)\ 3x +5 + (x+5) = (1-x)+4\\3x + 5 + x + 5 = 1 - x + 4\\4x + x = 1+4 - 5 - 5\\5x = -5\\x = -5 : 5\\x = -1;\\\\3) -3x + 1 + (x-5) = 5(3 - x) + 5\\-3x + 1 + x -5 = 15 - 5x + 5\\-2x+5x = 20 - 1 + 5\\3x = 24\\x = 24 : 3\\x = 8;\\\\4)\ 4x + 4 -3(x+1) = 5(-2-x)+5\\4x + 4 -3x -3 =-10-5x+5\\x + 5x = -5-4+3\\6x = - 6\\x = -6 : 6\\x = -1;$

$5)\ 3x + 5 + (x+5) = (1-x) + 4\\3x + 5 + x + 5 = 1 - x + 4\\4x + x = 5 - 5 - 5\\5x = -5\\x = -5 : 5\\x = -1;\\\\6)-3x + 1-3(x+3) = -2(1-x)+2\\-3x+1 - 3x - 9 = -2 + 2x + 2\\-6x - 2x = 0 -1 + 9\\-8x = 8\\x = 8 : (-8)\\x = -1.$
