Решите уравнение x+2=4-x,3x+1=5x-3,2x-3=2-3x,2x+3=3x-7,9x-2=5x-2,10-3x-2x-15,10x+7=8x-9,53-6x=4x-17,8+2x=16+x

Найдем корни.

1) x + 2 = 4 - x;

x + x = 4 - 2;

2 * x = 2;

x = 2/2;

x = 1.

2) 3 * x + 1 = 5 * x - 3;

3 * x - 5 * x = -3 - 1;

-2 * x = -4;

x = 4/2;

x = 2.

3) 2 * x - 3 = 2 - 3 * x;

2 * x + 3 * x = 2 + 3;

5 * x = 5;

x = 1.

4) 2 * x + 3 = 3 * x - 7;

2 *  x - 3 * x = -7 - 3;

x = 10;

5) 9 * x - 2 = 5 * x - 2;

9 * x - 5 * x = -2 + 2;

x = 0.

6) 10 - 3 * x = 2 * x - 15;

-3 * x - 2 * x = -15 - 10;

5 * x = 25;

x = 5.

7) 10 * x + 7 = 8 * x - 9;

10 * x - 8 * x = -9 - 7;

x = -8.

8) 53 - 6 * x = 4 * x - 17;

-6 * x - 4 * x = -17 - 53;

-10 * x = -70;

x = 7.

9) 8 + 2 * x = 16 + x; 

2 * x - x = 16 - 8; 

x = 8.
