The value of x for given equation (2x - 20) /3 = 2x is x = -5
For given question,
we have been given an equation 2x minus 20 divided by 3 = 2x
i.e., (2x - 20) /3 = 2x
This equation models temperature change, where x represents the difference in degrees in the last 24 hours.
We need to solve given equation for x.
(2x - 20) /3 = 2x
(2x - 20) = 3(2x) ...........(Multiply by 3 on both sides)
2x - 20 + 20 = 6x + 20 ...........(Add 20 to both sides)
2x - 6x = 6x + 20 - 6x ..........(Subtract 6x from both sides)
-4x = 20
x = -5 ..........(Divide by - 4 on both sides)
Therefore, the value of x for given equation (2x - 20) /3 = 2x is x = -5
