Final answer:
To solve the equation D+g=4ha for a, subtract g from both sides and then divide by 4h.
Step-by-step explanation:
To solve the equation D+g=4ha for a, we need to isolate the variable a on one side of the equation. Here's how to do it:
Step 1: Subtract g from both sides of the equation to move it to the other side:
D+g-g=4ha-g
D=4ha-g
Step 2: Divide both sides of the equation by 4h:
D/(4h)=(4ha-g)/(4h)
a=(D-g)/(4h)
So, the value of a is (D-g)/(4h).
