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
