Решите уравнения:5-1/2*(2х-6)-3*(3-х)1-2*(3х+4)=5+6х20*(10х)-200*(-9х)=2005-4х=3*(1-2х)+1

Answer 1

1)3х-х+5+6-9=0
2х+2=0
х=-1

Answer 2

5-1/2*(2x-6)-3*(3-x) = 1-2*(3x+4) First, we simplify both sides of the equation.

5 - 1*(2x-6) - 3*(3-x) = 1 - 2*(3x+4) 5 - 2x + 6 - 9 + 3x = 1 - 6x - 8 -2x + 2x - 3x + 3x = -13 - 6x 0 = -13 - 6x 6x = -13 x = -13/6

20*(10x) - 200*(-9x) = 200 200x - (-1800x) = 200 200x + 1800x = 200 2000x = 200 x = 200/2000 x = 1/10

5 - 4x = 3*(1-2x) + 1 5 - 4x = 3 - 6x + 1 5 - 4x = 4 - 6x 6x - 4x = 4 - 5 2x = -1 x = -1/2

So, the solutions to the equations are: x = -13/6, x = 1/10, and x = -1/2.
