Answer:
2
Explanation:
2 is the coefficient, it is being multiplied by x.
X is the variable in this equation its value is not set and it is unknown.
12 is the constant, its value does not change because it isnt being multiplied/divided by anything.
The coefficient is always the number with x. In this case 2x, so 2 is the coefficiente, if it is a single number, 12 in this case, is called constant.
