2D + 4 = 10 + 2.5D: Solving the Equation
In this article, we will solve the equation 2D + 4 = 10 + 2.5D.
The Given Equation
The equation is:
2D + 4 = 10 + 2.5D
Step-by-Step Solution
To solve for D, we will follow the steps below:
Step 1: Combine like terms
Combine the D terms on the left-hand side of the equation:
2D + 4 = 10 + 2.5D
Subtract 2.5D from both sides:
2D - 2.5D + 4 = 10
This simplifies to:
-0.5D + 4 = 10
Step 2: Isolate D
Subtract 4 from both sides:
-0.5D = 10 - 4
-0.5D = 6
Divide both sides by -0.5:
D = -6 / 0.5
D = -12
The Final Answer
Therefore, the value of D is:
D = -12
So, the correct answer is D = -12.
