28 + (3x -2) + 28 = 6x
28+ (3x -3x -2) + 28 = 6x - 3x
28+ (-2) + 28 = 3x
28 - 2 + 28 = 3x
26 + 28 = 3x
54 = 3x
18 = x
Answer:
x = 4 1/2
Step-by-step explanation:
To get to minus 1/2 from plus 2 you would subtract 2 1/2 from 2.
To arrive at x you would add 2 1/2 to 2.
The result is a progression of: 4 1/2, 2, - 1/2
(4 1/2 minus 2 1/2 = 2; 2 minus 2 1/2 = - 1/2)
original price:480
how:
x=80×6 or x=80/(1/6)
=480
check: 480/6 or 480×(1/6)
=80
:) hope this helped!
