2 - (2t + 1) = 4(t + 2)
First you want to distribute the 4 on the right side to everything in the brackets by multiplying both terms by 4
2 - (2t + 1) = 4t + 8
Then you want to add (2t + 1) to both sides
2 = 4t + 8 + (2t + 1)
Now you can get rid of the brackets
2 = 4t + 8 + 2t + 1
Simplify
2 = 6t + 9
Minus 9 on both sides
-7 = 6t
Divide by 6 on both sides
-1.17 = t
