What is the solution of the equation 0.2x - 2.15 = -8.27?

Question

-30.6

-52.1

-1.224

-3.06

Answer 1

To solve the equation $0.2x-2.15=-8.27$, follow these steps:

1. First, isolate the term with $x$ by adding $2.15$ to both sides of the equation:

   $$0.2x-2.15+2.15=-8.27+2.15$$

   Simplifying this gives:

   $$0.2x=-6.12$$

2. Next, solve for $x$ by dividing both sides by $0.2$:

   $$x=\frac{-6.12}{0.2}$$

3. Performing the division:

   $$x=-30.6$$

Therefore, the solution of the equation $0.2x-2.15=-8.27$ is $\boxed{{\displaystyle -30.6}}$.
