решите уравнения 2(х+2)-3(х-2)=5-4(3х-1) и 2(2х-1)-3(х-2)=6+4(3-2х)

Question

решите уравнения 2(х+2)-3(х-2)=5-4(3х-1) и 2(2х-1)-3(х-2)=6+4(3-2х)

Answer 1

2(х+2)-3(х-2)=5-4(3х-1)

2x+4-3x+6=5-12x+4

11x=-1

x=-1/11

 

2(2х-1)-3(х-2)=6+4(3-2х)

4x-2-3x+6=6+12-8x

9x=14

x=14/9

 

Answer 2

2x+4-3x+6=5-12x+4;  2x-3x+12x=5+4-4-6;   11x=-1 x=-1/11                                        2)4x-2-3x+6=6+12-8x; 4x-3x+8x=6+12+2-6;9x=14 x=14/9
