Question

Solve 8t + 16 > 16t - (12t - 20).
Question 3 answers
{t| t > 1}
{t| t > -1}
{t| t < 4}
{t| t > 4}

Answer 1

Distribute the negative on the right
8t+16>16t-12t+20
Combine on the right
8t+16>4t+20
Subtract 4t
4t+16>20
Subtract 16
4t>4
Divide by 4
t>4
So the last option if you want it in set notation:
\[\left\{ t|t>4 \right\}\]

Answer 2

Errrrr t>1 so the first option. I feel retarded lol 4/4=4? Doubt it.
