17t + 4t − 5t − 13t = 18
do 17t+4t first
21t-5t-13t
21t-5t and then do -13t
16t-13t= 18
3t= 18
divide both sides by 3 to get t by itself
3t/3= 18/3
cross out 3 and 3, divide by 3 and then becomes 1*1*t= t
t= 18/3
Answer:
t= 6
Step-by-step explanation:
Isolate t on one side of the equation.
17+4t-5t-13t=3t (Combine like terms & group like terms )
3t=18
3t/3=18/3 (Divide by 3 from both sides.)
18/3 (Solve.)
18/3=6
t=6
Therefore, the final answer is t=6.
