I'm going to assume that you mean 5t = 3t - 10. You solve for t in the following way. First combine like terms by subtracting 3t from both sides of the equation: 5t - 3t = 3t - 3t - 10, 2t = -10. Next, isolate t by dividing both sides of the equation by 2: 2t/2 = -10/2, t = -5. To verify that this is the solution, plug this value of t back into the original equation: 5(-5) = 3(-5) - 10, -25 = -15 - 10, -25 = -25. Since -25 does in fact equal -25, our value for t is correct.
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
It is an equation. Taking it step by step: 17 = 3t - 4 17 + 4 = 3t 21 = 3t 7 = t So the value of t is 7.
t = -11/10
Yes and t = 1 in both equations
3t+11 = 29 3t = 29-11 3t = 18 t = 6
s = 7, t = -3
3t - 15 = -9 3t - 15 (+15) = -9 (+15) 3t = 6 3t (/3) = 6 (/3) t = 2
5-3t = 0.77 -3t = 0.77-5 -3t = -4.23 t = 1.41
