Решите уравнения: 1) 5x+(3-2x)=14 2) 7x-(8x+4)=-3 3) 4-3(5x-6)=-3x 4) 2(4x+6)-5x=10

5х + (3 – 2х) = 14
5х + 3 – 2х = 14
3х + 3 = 14
3х = 14 – 3
3х = 11
х = 11 : 3
х = 11/3

7х – (8х + 4) = – 3
7х – 8х – 4 = – 3
– х – 4 = – 3
– х = – 3 + 4
– х = 1
х = – 1

4 – 3(5х – 6) = – 3х
4 – 15х + 18 = – 3х
22 – 15х = – 3х
– 15х + 3х = – 22
– 12х = – 22
х = 11/6

2(4х + 6) – 5х = 10
8х + 12 – 5х = 10
3х + 12 = 10
3х = 10 – 12
3х = – 2
х = – 2/3
