you can pick which equation you want to do, i am picking the first one. 2(t+1)=10. first we simply the equation, we do this by multiplying the number outside of the parenthesis, 2, by t and 1. 2*t=2t, and 2*1 = 2, so he equation we have to solve is 2t+2=10. we can subtract 2 from the 2, and subtract 2 from the ten, so our equation is no 2t=8, 2* what equals 8, we know that 2*4=8, so t=4
