9t + 5 = 7 - 2t
Subtract five from both sides:
9t = 2 - 2t
Add 2t to both sides:
11t = 2
Divide both sides by 2
t = 2/11 or about .1818

9t = 4t + 120 9t-4t = 4t - 4t + 120 5t = 120 5t/5 = 120/5 t = 24 24 is your answer
9t+6, but you would need answer to t or you would need the answer to the equation
2t^2+5t-3=0 (2t-1)(t+3)=0 2t-1=0 and t+3=0 t=.5 and t=-3
-t + 9 = t + 5(if it helps, you can pretend there is a 1 in front of each t)-1t + 9 = 1t + 5Add 1t to both sides-1t + 1t + 9 = 1t + 1t + 5(Keep the variable on the left of the equals sign lessens confusion, so let's flip the terms)9 = 2t + 52t + 5 = 9Subtract 5 from both sides2t + 5 - 5 = 9 - 5Divide both sides by 22/2t = 4/2t = 2
That's entirely correct.If you divide each side of the equation by 't',you reach the startling conclusion that 5 = 5 !
