1 x 97, 97 x 1 = 97
67 = x + 97-30 = x
1 x 97.
1 x 97 = 97
97 * 10 = 970
The number 97 multiplied by itself equals 97: 97 x 1 = 97
97 x 1 98 - 1 96 + 1 96/1
6x+13 = 97-6 6x = 97-6-13 6x = 78 x = 13
X = 12
Take logs of both sides - you can use any base, to give the answer: 10^x = 97 → log(10^x) = log(97) → x log(10) = log(97) → x = log(97) ÷ log(10) If you use common logs (logs to base 10) - highly recommended in this case), then: lg(10) = 1 → x = lg(97)
2x + 21 = 97 2x = 76 x = 38 Check it. 5 x 38 + 21- 3 x 38 190 + 21 - 114 211 - 114 = 97 It checks.
x = 77 x + 20 = 97 x = 97 - 20 x = 77
