-8-9t=21t-17 Start with the given equation



-9t=21t-17%2B8Add 8 to both sides


-9t-21t=-17%2B8 Subtract 21t from both sides


-30t=-17%2B8 Combine like terms on the left side


-30t=-9 Combine like terms on the right side


t=%28-9%29%2F%28-30%29 Divide both sides by -30 to isolate t



t=3%2F10 Reduce

--------------------------------------------------------------
Answer:
So our answer is t=3%2F10 (which is approximately t=0.3 in decimal form)
