10(line)2-4a(line)=20

Absolute value
How do I solve this equation?

To solve the equation, you need to isolate the variable "a". Here's how:

Step 1: Start by simplifying the equation. Distribute the 10 to the terms inside the parentheses:
10 - 2a - 4a = 20

Step 2: Combine like terms:
10 - 6a = 20

Step 3: Subtract 10 from both sides to move the constant term to the other side:
-6a = 10

Step 4: Divide both sides by -6 to solve for "a":
a = -10/6, or simplified as a = -5/3
