Question

Решите уравнение:
1) 4x+5(3-2x)=5-11x
2) 19-2(3x+8)=2x-37
3) 8x+3(7-2x)=4x+3
4) 23-4(3x+8)=1-17x

Answer 1

1) 4x - 15 - 10x - 5 + 11x = 0;

-3x - 20 = 0;

x = -20/3.

2) 19 - 6x - 16 - 2x + 37 = 0;

-8x +40 = 0;

x = 5;

3) 8x + 21 - 6x - 4x - 3 = 0;

-2x + 18 = 0;

x = 9;

4) 23 - 12x - 32 - 1 + 17x = 0;

5x - 10 = 0;

x = 2.
