I am assuming your teacher wants you to solve for v.
Therefore we need to isolate v, first step will be moving 2 to the other side then multiplying both sides by 11.
4=v/11-2
4+2=v/11
6=v/11
6*11=v/11*11
66=v
v=66
Check answers: substitute v=66 back into the equation.
right hand side:66/11-2=6-2=4
left hand side:4
RHS=LHS therefore the solution is correct.
Done!
