What is the solution of the equation 0.2x−2.15=−8.27 ?(1 point)
−3.06
−30.6
−1.224
−52.1
To solve the equation 0.2x - 2.15 = -8.27, we want to isolate the variable x.
First, we can 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
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
x = -30.6
Therefore, the solution to the equation is x = -30.6.
To solve the equation 0.2x - 2.15 = -8.27, you can follow these steps:
Step 1: Add 2.15 to both sides of the equation to isolate the term with x:
0.2x = -8.27 + 2.15
Step 2: Simplify the right side of the equation:
0.2x = -6.12
Step 3: Divide both sides of the equation by 0.2 to solve for x:
x = -6.12 / 0.2
Step 4: Simplify the expression:
x = -30.6
Therefore, the solution to the equation 0.2x - 2.15 = -8.27 is x = -30.6.
So, the correct answer is -30.6.
To find the solution of the equation 0.2x - 2.15 = -8.27, we need to isolate the variable x. Here's how you can do it step by step:
1. Start by adding 2.15 to both sides of the equation to get rid of the -2.15 term:
0.2x - 2.15 + 2.15 = -8.27 + 2.15
Simplifying this, we have:
0.2x = -6.12
2. We then divide both sides of the equation by 0.2 to solve for x:
0.2x/0.2 = -6.12/0.2
Simplifying this, we have:
x = -30.6
Therefore, the solution to the equation 0.2x - 2.15 = -8.27 is x = -30.6. So, the correct answer is -30.6.
