First you have to distribute the -3 to the 2t and the 1. That equals -6t and -3. Then, you have to make the -3 go to the other side that way you could leave the t alone. This means the -3 becomes a +3. -3+3=0 Next you have to divide the -6 with the zero that way the t is isolated (left alone). This equals 0. Which means that t=0.
Hope this helps!
