Answer:
24
Step-by-step explanation:
the value of a is 2, therefore 7x2=14 and 12x2=24
Answer: a=2
Step-by-step explanation: Well when we look at 7a = 14 how did we get to 14? Well, 7 times 2 equals 14 correct? so, we know that the variable a must equal 2. We then need some answer for 12a = __. We will need to use what we learned from the first problem which was that a equaled 2. Therefore 12a = 24.
