4a. 6x + 5 = 26 - x
6x + x = 25 - 5
7x = 21
x = 21/7 = 3
b. 2 - 4x = 3
-4x = 3-2
-4x = 1
x = -1/4
c. x - 12 = 2x + 36
x - 2x = 36 + 12
-x = 48
x = -48
d. -5x - 4x + 10 = 1
-9x = 1 - 10
- 9x = -9
x = 1
e. 2 + x/4 = 5
8 + x = 20
x = 20 - 8
x = 12
5. 3x + 12 = 7x - 8
3x - 7x = -8 - 12
-4x = -20
x = 20/4 = 5
Nilai x + 2 = 5 + 2 = 7
