1. x = 2
2. x= 4
3. m= 3
4. y = - 21/4
5. x= 17/3
6. n = -3
Explicación paso a paso:
1. 6x - 10 = 2 6x = 2 + 10 x = 12/6 x= 2
2. -2 + 3x = 10 3x = 10 + 2 x = 12/3 x = 4
3. 4m + 2 = 20 - 2m 4m + 2m = 20 - 2 6m = 18 m = 18/6 m = 3
4. -3(2y + 3) = -10 ( y + 3 )
-6y - 9 = -10y - 30
- 6y + 10y = -30 + 9
4y = -21
y = - 21/4
5. 2(1/3) + 3(2/4) - x = 0
7/3 + 10/3 - x = 0
7/3 + 10/3 = x
17/3 = x
6. 2(3 - 5n) = 36
6 - 10n = 36
- 10 n = 36 - 6
-10n = 30
n = -30/10
n = -3
