Answer:The answer is t=-12
Step-by-step explanation: First you have to simplify so the 4 is now positive. 2(t+18)+4, Subtract 4 from both sides.
2(t+18)=16−4
=12, 2(t+18)=12, now you have to divide both sides by 2. 2t/2=t and 12/2=6. t+18=6 now just subtract 18 from both sides. 18-18=0, 6-18=-12. So the answer is t=-12.
