The video tutorial explains how to solve the equation 2 * X + a = 4 B by isolating the variable 'a'. It begins with understanding the role of parentheses and the distributive property. The tutorial then demonstrates how to simplify the equation and solve for 'a' by applying mathematical operations step-by-step, ensuring clarity in the process.

Why is the variable 'a' placed inside the parentheses in the equation 2 * X + a = 4 B?

• Because it is being added to X

• Because it is being multiplied by 2

• Because it is being divided by 2

• Because it is a constant

What property is used to simplify the equation 2X + 2A = 4B?

• Associative Property

• Commutative Property

• Distributive Property

• Identity Property

After applying the distributive property, what is the next step to isolate 'a'?

• Add 2X to both sides

• Subtract 2X from both sides

• Multiply both sides by 2

• Divide both sides by 4

What operation is performed to both sides of the equation to solve for 'a' after subtracting 2X?

• Divide by 2

• Add 2

• Multiply by 2

• Subtract 2

What is the final expression for 'a' after solving the equation?

• a = B - 2X

• a = 4B - 2X

• a = 2B - X

• a = 2B + X
