9t + 5(t+3) = -(t+13) + t
9t + 5t +15 = -t -13 + t
hence 9t + 5t = 14t and -t + t = 0 then
14t +15 = -13
14t = -28
-28 divide by 14
t = -28 / 14
t= -2
That is answer :D

9t + 5(t+3) = -(t+13) + t
9t + 5t +15 = -t-13+t
14t +15 = -13
14t =-28
---> t =-2

what is this? find t?
9t + 5(t+3) = -(t+13) + t
9t + 5t + 15 = -t - 13 + t
14t + 15 = -13
14t = -13 - 15
14t = -28...divide both side by 14
t = - 2

9t + 5(t+3) = -(t+13) + t
9t+5t+15=-t-13+t
14t+15=-13
14t=-28
t=-2

use the distributive property of multiplication
9t + 5t + 15 = -t -13 + t
combine like terms
14t + 15 = -13
use the transposition method
14t = -13 -15
14t = -28
t = -2
hope that helps =))

combine like terms and simplify
9t +5t + 15 = -t -13 + t
this becomes
14t + 15 = -13
subtract 15 from both sides to balance the equation
14t = -28
divide both sides by 14 to simplify
t = -2
