Question

Решите уравнение 2x- (-5x+2)= 1-2 (x-7) 5/6 - 2/3 x=3x+2

Answer 1

А) 5x-2=2x+7
 5х-2х=7+2;
3х=9;
х=9/3;
х=3.
б)3x-2=6+4x;
3х-4х=6+2;
-х=8;
х=-8
а)11+3x=55+4x3х-4х=55-11;-х=44;
х=-44;

б)-15-4x=-8x+45
 -4х+8х=45+15;
4х=60;
х=60/4;
х=15;
в) -8x-17=3x-105
-8х-3х=-105+17;
-11х=-88;
х=88/11;
х=8
