Respuesta:
* 2x - 3 = 4x - 7
2x - 4x = - 7 + 3
-2x = - 4
x = - 4/-2
x = 2
x = 2 * 5x + 4 = 6x + 3
5x - 6x = 3 - 4
-1x = -1
x= - 1/-1
x = 1
x = 1 * 6x - 1 = 8x - 5
6x - 8x = - 5 + 1
-2x = - 4
x = - 4/-2
x = 2
x = 2*3x + 10 =5x - 6
3x - 5x = - 6 - 10
-2x = - 16
x = - 16/-2
x = 8
x = 8 * 4x + 1 = 9x - 64
4x - 9x = - 64 - 1
-5x = - 65
x = - 65/-5
x = 13
x = 13 *7x + 6 = 9x - 2
7x - 9x = - 2 - 6
-2x = - 8
x = - 8/-2
x = 4
x = 4 * - 3x + 2= x + 10
-3x - x = 10 - 2
-4x = 8
x = 8/-4
x = - 2
x = - 2 * - 6x + 3 = - 2x +1
-6x +2x = 1 - 3
-4x = - 2
x = - 2/-4
x = 1/2
Explicación paso a paso:
Comprobación de cada ecuación:
* 2(2)-3=4(2)-7
4-3 = 8-7
1 = 1
* 5(1)+4 = 6(1)+3
5+4 = 6+3
9=9
*6(2)-1 = 8(2)-5
12-1 = 16 - 5
11 = 11
*3(8)+10 = 5(8)-6
24+10 = 40 + 6
34 = 34
* 4(13)+1 = 9(13) - 64
52+1 = 117 - 64
53 = 53
* 7(4)+6 = 9(4)-2
28+6 = 36-2
34 = 34
* - 3(-2)+2 = - 2+10
6+2 = 8
8 = 8
* - 6(1/2)+3 = - 2(1/2)+1
-3+3 = - 1+1
0 = 0
