2 Step equation:

-17 + b/8 = 13

7 (c-12) = - 21

-3 + P/7 = - 5

46 = - 6t - 8

-17 + b/8 = 13

+17 + 17

b/8 = 30

x8 x8

b = 240

(-17 + 240/8 = 13 = - 17 + 30 = 13 = 13 = 13)

7 (c - 12) = - 21

7c - 84 = - 21

+84 + 84

7c = 63

/7 / 7

c = 9

(7 (9-12) = - 21 = 63 - 84 = - 21 = - 21 = - 21)

-3 + P/7 = - 5

+3 + 3

P/7 = - 2

x7 x7

P = - 14

(-3 + - 14/7 = - 5 = - 3 + - 2 = - 5 = - 5 = - 5)

46 = - 6t - 8

+8 + 8

54 = - 6t

/-6 / - 6

-9 = t

(46 = - 6 (-9) - 8 = 46 = 54 - 8 = 46 = 46)
