<h3>Given</h3>
... r + 7 = 9
<h3>Find</h3>
... r
<h3>Solution</h3>
Subtract 7 from both sides of the equation.
... r + 7 - 7 = 9 - 7
... r = 2 . . . . . . simplify
Expressed as a solution set, this may look like ...
... r ∈ {2}

You probably had no trouble solving this in 2nd grade when it was shown to you in the form ...
__ + 7 = 9
If 8 3/4 is 25% (1/4) of a number, you can multiply 8 3/4 (8.75) by 4 to get the answer, because 1/4 multiplied by 4 equals one.
(you should get 35)
I can’t see 9 and 10 but the answer to 17 would be 25 yards farther
4 = 12
10 = 18
22 = 30
54 = 62
62 = 70
100 = 108
