1 ) t - 285 : 19 = 66.

t - 15 = 66.

t = 66 + 15.

t = 81.

2 ) x + 405 : 27 = 41.

x + 15 = 41.

x = 41 - 15.

x = 26.

3 ) 82 - 8x = 18.

82 - 18 = 8x.

64 = 8x.

x = 64 / 8.

x = 8.

4 ) 741 : (m + 25) = 19.

m + 25 = 741 / 19.

m + 25 = 39.

m = 39 - 25.

m = 14.

5 ) (27x + 252) : 18 = 53.

27x + 252 = 53 * 18.

27x + 252 = 954.

27x = 954 - 252.

27x = 702.

x = 702 / 27.

x = 26.

6 ) 91 - 13x = 13.

91 - 13 = 13x.

78 = 13x.

x = 78 / 13.

x = 6.
