Question

Hello everyone can you answer this for me? What is A in the equation attached? Please and thank you.

Answer 1

Answer:

a = 6

Step-by-step explanation:

Hello!

Solve:

• 4(3a - 4) = 56
• 3a - 4 = 14          (factoring out 4)
• 3a = 18               (adding 4 to both sides)
• a = 6                   (dividing by 3)

Another way:

• 4(3a - 4) = 56
• 12a - 16 = 56        (distributive property)
• 12a = 72               (moving like terms)
• a = 6                    (dividing by 12)

Distributive Property of Multiplication:

The process of distributing the outside factor to the terms in the parenthesis.

Example:

$4(3a - 4)\\\\4(3a) - 4(4)\\\\12a - 16$
