1. 0.2x-2.15=-8.27

Answer 1

To solve the equation 0.2x - 2.15 = -8.27, we need to isolate the variable x.

We can start by adding 2.15 to both sides of the equation to eliminate the constant term on the left side:

0.2x - 2.15 + 2.15 = -8.27 + 2.15

This simplifies to:

0.2x = -6.12

Next, we can divide both sides of the equation by 0.2 to solve for x:

(0.2x) / 0.2 = -6.12 / 0.2

This gives us:

x = -30.6

So, the solution to the equation 0.2x - 2.15 = -8.27 is x = -30.6.
