To solve the equation 2.8X - 1.2X = 8, we first combine like terms:
2.8X - 1.2X = 8
(2.8 - 1.2)X = 8
1.6X = 8
Next, we isolate X by dividing both sides of the equation by 1.6:
1.6X / 1.6 = 8 / 1.6
X = 5
Therefore, the solution to the equation 2.8X - 1.2X = 8 is X = 5.
2.8X - 1.2X = 8
(2.8 - 1.2)X = 8
1.6X = 8
Next, we isolate X by dividing both sides of the equation by 1.6:
1.6X / 1.6 = 8 / 1.6
X = 5
Therefore, the solution to the equation 2.8X - 1.2X = 8 is X = 5.
