For part A, first of all, you need to multiply both sides by 2.
4x - 1 = 2x + 14
Then, you need to add 2 to both sides.
4x = 2x + 15
Now, you need to subtract 2x from both sides.
2x = 15
Finally, you need to divide both sides by 2.
x = 7.5
So the answer to part A is 7.5
Now for part B.
First of all, you need to multiply both sides by 3.
9x + 6 = 2x + 13
Next, you need to subtract 6 from both sides.
9x = 2x + 7
Now, you need to subtract 2x from both sides.
7x = 7
Finally, you need to divide both sides by 7.
x = 1
So the answer to part B is 1
