Answer
t=6
Work Step by Step
2t-1=11. In this kind of problem, remember to take the whole expression with variable(s) on one side and to put numbers on another side. To get rid of -1, add 1 to both side. 2t-1+1=11+1 =>2t=12.If you want to get rid of 2, divide both side by 2 (notice: do the opposite operation to get rid of what you want.) 12$\div$2=t=> t=6
