Answer:
4
Step-by-step explanation:
Solving:
- 1.5(a -4) - 2 = 4
- 1.5a - 6 -2 = 4
- 1.5a - 8 = 4
- 1.5a = 4 + 8
- 1.5a = 12
- a = 12/1.5
- a = 8
Checking:
- 1.5(8-4) - 2 = 4
- 1.5*4 - 2 = 4
- 6 - 2 = 4
- 4 = 4
Solution :
5a -20 - 2 = 4
5a - 22 = 4
5a = 4 + 22
5a = 26
a = 26/5
a = 5.2
Check :
5(5.2 - 4 ) - 2 = 4
26 - 20 - 2 = 4
6 - 2 = 4
4 = 4
