17t + 4t - 5t - 13t = 18

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

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.
