Answer:
t = 1
Explanation:
16 - 2t = t + 9 + 4t
Group like terms
16 - 2t = t + 4t +9
Add similar elements t + 4t = 5t
16 - 2t = 5t + 9
Subtract 16 from both sides
16 - 2t - 16 = 5t + 9 - 16
Simplify
-2t = 5t - 7
Subtract 5t from each side
-2t - 5t = 5t - 7 - 5t
Simplify
-7t = -7
Divide both sides by -7
-7t/ -7 = - 7/ - 7
Simplify
t = 1
