We can use the distribution method for this:

1/2r - 3 = 2(4 - 3/2r)

Multiply 2 by everything inside the parentheses:

1/2r - 3 = 8 - 3r.

Move variables to one side, and numbers to another:

1/2r + 3r = 8 + 3.

3 1/2r = 11.

7/2r = 11.

Divide by 7/2:

r = 22/7.

Not sure this is correct.

omeli [17]
So in order to solve you must first combine like terms.
-2y + 2y + 3 = 3
0 + 3 = 3
Subtract 3.
0 = 0
The answer is infinate solution because both numbers are the same.
I hope this helps love! :)
