Step A, I believe. First you have to distribute but after you distribute, you subtract the 15. With 15 being the bigger number, it is left with a negative 3. Hope this helps!

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression 3(4x + 5) = 12 will be solved as below:-

3(4x + 5) = 12

Multiply by 3 in the first step and write the expression.

12x + 15 = 12

Take constant on the same side and solve the expression.

12x = 12-15

12x = -3

Hence, the correct option is A.
