-7t=91
or t=-13
8 X 7t = 56t Answer: 7t
If: 7t = x Then: t = x/7
-7t = 42Multiply each side by -1:7t = -42Divide each side by 7:t = -6
t= -6
t = -14
t = -11/10
-47
2 (t = -1)
5t - 7t = -2
7t
(7t³ + 2k4)(7t³ - 2k4)
8. To solve this problem, plug the given t value into the equation. So, given the equation 7t-6 and that t=2, I get 7(2) - 6. This is the same as 14-6, which is 8
