Do what the problum ids telling you than apply it to the math and you will always get the right answer
The answer is 58 pretty sure
First, subtract 7 on both sides. Now, you have 4x<1. Divide by 4 on both sides. Finally, you get x<1/4 (a quarter or said as one-fourth). So, x<1/4.
The answer to your question is B.7/16.
The explanation for this is that 3/8 is in 16ths, 6/16, and 7/16 is greater than 6/16!

The coefficient is 12a because it has a variable (a).
