d−21.4=87.9
d = 109.3
Step 1: Add 21.4 to both sides of the equation.
d - 21.4 + 21.4 = 87.9 + 21.4
Step 2: Simplify the equation.
d = 109.3
To solve the equation d - 21.4 = 87.9, you need to isolate the variable d by performing the same operation on both sides of the equation.
Step 1: Start by adding 21.4 to both sides of the equation:
d - 21.4 + 21.4 = 87.9 + 21.4
This simplifies to:
d = 109.3
Step 2: Therefore, the solution to the equation is d = 109.3.
To solve the equation d - 21.4 = 87.9, follow these steps:
Step 1: Add 21.4 to both sides of the equation to isolate the variable "d":
d - 21.4 + 21.4 = 87.9 + 21.4
Simplifying, we get:
d = 109.3
