That's entirely correct.If you divide each side of the equation by 't',you reach the startling conclusion that 5 = 5 !
89+2t = 10t+25 89-25 = 10t-2t 64 = 8t t = 8

t - 2t - 3t = 32t - 5t = 32-4t = 32t = -8According to the information given in the question, t can't equal 8.

(2t - 3)(7t^2 + 8)
2t+8-t=-3(t+t)+8-t=-3-8 -8(t+t)-t=-11the -t and the +t cancel outt=-112(-11)+8-(-11)=-3-22+8+11=-3
12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
2t - 8 = 3t + 12 First you remove the outer numbers from one side of the equation. In this case, 12. But whatever you do to one side, you have to do the same for the other side. 2t - 8 - 12 = 3t Then put all the terms with unknowns on one side. -8 - 12 = 3t - 2t We can simplify this into... -20 = t so... t = -20. hope that helps. :)
