To solve the equation 0.2x - 2.15 = -8.27, we can start by isolating the variable x by performing the necessary operations:
0.2x - 2.15 = -8.27
First, add 2.15 to both sides of the equation to get rid of the constant term on the left side:
0.2x - 2.15 + 2.15 = -8.27 + 2.15
Simplifying,
0.2x = -6.12
Next, divide both sides of the equation by 0.2 to solve for x:
(0.2x)/0.2 = -6.12/0.2
This results in:
x = -30.6
Therefore, the solution to the equation 0.2x - 2.15 = -8.27 is x = -30.6.
