Answer:
x = 8
Step-by-step explanation:
So, first thing first, we need to push all of the variables to different sides.
2x - 1 = 3/4x + 9, we move the +9 to the other side and get;
2x - 10 = 3/4x
Now we can just multiply both sides by 4 and we get:
8x - 40 = 3x
Now that there are no more fractions, we can just take away 8x from both sides to get;
-40 = -5x, or if we multiply the whole equation by -1 we get;
40 = 5x
Now its a simple matter of dividing both sides by five and we get;
x = 8
