Salutare!
a)
3 - 6x = 2 - 4x
-6x + 4x = 2 - 3
-2x = -1
x = -1 / -2
x = 1/2
b)
2x + (3 - 6x) = -17
2x + 3 - 6x = -17
2x - 6x = -17 - 3
-4x = -20
x = -20 / -4
x = 20 / 4
x = 5
c)
2 (x + 1) = 3 (x - 1)
2x + 2 = 3x - 3
2x - 3x = -3 - 2
-x = -5
x = -5 / -1
1) 2x + (3 - 6x) = -17
3 - 6x = -17 - 2x
3 - 6x + 17 + 2x = 0
20 - 4x = 0
20 = 4x
2) 2(x + 1) = 3(x - 1)
2x + 2 - 3x + 3 = 0
-x + 5 = 0
3) 3 - 6x = 2 - 4x
3 - 6x - 2 + 4x = 0
1 - 2x = 0
1 = 2x
x = [tex]\frac{1}{2}[/tex]
Sper că te-am ajutat ;)
