Please show the work
Alex Ar [27]

Step-by-step explanation:

15t + 30 = 20t | -15t

30 = 5t

t = 30/5 = 6

20 + 5t = -6t + 86 | + 6t

20 + 11t = 86 | -20

11t = 66

t = 6

18t + 20 = 24t + 50 | -18t

20 = 6t + 50 | -50

-30 = 6t

t = -30/6 = -5

18t - 2 = 10t + 54 | -10t

8t - 2 = 54 | +2

8t = 56

t = 56/8 = 7

7t - 5 = 15t + 91 | -7t

-5 = 8t + 91 | -91

-96 = 8t

t = -96/8 = -12
