16=2(t-1)-1
We move all terms to the left:
16-(2(t-1)-1)=0
We calculate terms in parentheses: -(2(t-1)-1), so:We get rid of parentheses
2(t-1)-1
We multiply parentheses
2t-2-1
We add all the numbers together, and all the variables
2t-3
Back to the equation:
-(2t-3)
-2t+3+16=0
We add all the numbers together, and all the variables
-2t+19=0
We move all terms containing t to the left, all other terms to the right
-2t=-19
t=-19/-2
t=9+1/2
