Eliana Gibson · Answer 1

2t+21=3 (t+5) Take it out of parenthesis

2t+21=3t+15 Subtract 3t on both sides

-t+21=15 Subtract 21 on both sides

-t=-6 divide by - 1 on both sides to make the t positive

t=6

Janet Bell · Answer 2

Multiply it out and then subtract 2T from both sides as well as subtracting 15 from both sides. You wind up with six equals T
