Решите уравнение. 1) 5х = 32 + х; 2) 4х + 16 = 28 - 2х; 3) -3(х - 1) = 24 - 10х; 4) 2(4х + 5) - 3(х + 6) = 9х + 8;

1) 5х = 32 + х;5х - х = 32;4х = 32;х = 32 : 4;х = 8.

2) 4х + 16 = 28 - 2х;4х + 2х = 28 - 16;6х = 12;х = 12 : 6;х = 2.

3) -3(х - 1) = 24 - 10х;-3х + 3 = 24 - 10х;-3х + 10х = 24 - 3;7х = 21;х = 21 : 7;х = 3.

4) 2(4х + 5) - 3(х + 6) = 9х + 8;8х + 10 - 3х - 18 = 9х + 8;8х - 3х - 9х = 8 + 18 - 10;-4х = 16;х = 16 : (-4);х = -4.
