0.9v - 3.3 = 5.3v + 7.1 - 7.2v + 4.3

First, combine like terms on the right side of the equation:

0.9v - 3.3 = -1.9v + 11.4

Next, move all the v terms to one side by adding 1.9v to both sides:

2.8v - 3.3 = 11.4

Now, move the constant term to the other side by adding 3.3 to both sides:

2.8v = 14.7

Finally, divide by 2.8 to solve for v:

v = 14.7 / 2.8
v = 5.25

Therefore, the solution to the equation is v = 5.25.
