<u>On the first part, just replace the variables with the given number to check. </u>
1) 34 + 12 = 46 → <u>Correct</u>
2) 22 - 9 = 14 → <u>Incorrect</u>
3) 6 * 9 = 54 → <u>Correct</u>
4) 39 ^ 3 = 13 → <u>Correct</u>
<u />
<u>On the second part, simply change the symbols. Like this:</u>
5) 7 + k = 11 ⇒ 11 - 9 = k
<u>K = 2 </u>
6) p - 24 = 13 ⇒ 13 + 24 = p
<u> p = 37 </u>
7) b - 16 = 7 ⇒ 7 + 16 = b
<u>b = 23</u>
8)
+ m =
⇒
-
= m
<u>m = 13/30</u>
