a)2x + 3 * (x-2)= x-10
2x + 3x - 6 = x-6
5x - 6 = x - 6 | -x
4x - 6 = - 6 | 6
4x = 0
x = 0
b)
x/2 = 2x + 1/3 | 6
3x = 12x + 2 | - 3x
0 = 9x + 2 | -2
-2 = 9x | 9
-2/9 = x
2x+3x-6=x-10
5x-x= -10+6
4x = -4/:4
X = -1
X/2= 2x +1/3
3x = 12x+2
3x-12x=2
-9x= 2
X = -2/9
5x-x= -10+6
4x = -4/:4
X = -1
X/2= 2x +1/3
3x = 12x+2
3x-12x=2
-9x= 2
X = -2/9
