Answer 1

Ответ:

Answer 2

To solve the equation 54(a - 12) = 67 + 7, you'll need to follow these steps:

Step 1: Simplify both sides of the equation.

On the left side, distribute 54 to both terms inside the parentheses:

54(a - 12) = 54a - 648

On the right side, simplify 67 + 7:

67 + 7 = 74

So, the equation becomes:

54a - 648 = 74

Step 2: Add 648 to both sides of the equation to isolate the term with 'a' on the left side:

54a - 648 + 648 = 74 + 648

This simplifies to:

54a = 722

Step 3: Finally, divide both sides by 54 to solve for 'a':

54a / 54 = 722 / 54

a = 13.37 (rounded to two decimal places)

So, the solution to the equation is approximately a ≈ 13.37.
