5/2v-4=7/2v
what do you think you should do first?
5/2v-4=7/2v
Subtract 5/2v from both sides.
-4=v
correct,

To solve the equation 5/2v - 4 = 7/2v, we can follow these steps:
Step 1: Get rid of the fractions by multiplying both sides of the equation by the common denominator, which is 2. This will give us:
2 * (5/2v - 4) = 2 * (7/2v)
Simplifying this expression, we get:
5v - 8 = 7v
Step 2: Now, we want to isolate the variable v on one side of the equation. To do that, we can subtract 5v from both sides:
5v - 5v - 8 = 7v - 5v
This simplifies to:
-8 = 2v
Step 3: Finally, to solve for v, we divide both sides of the equation by 2:
-8/2 = 2v/2
This gives us:
-4 = v
Therefore, the solution to the equation 5/2v - 4 = 7/2v is v = -4.
