<h3><u>
The value of a is equal to 5.5</u></h3>
-22 = 11 - 6a
<em><u>Add 6a to both sides.</u></em>
6a - 22 = 11
<em><u>Add 22 to both sides.</u></em>
6a = 33
<em><u>Divide both sides by 6.</u></em>
a = 5.5
I believed it is "401"
1-9 = 9 digits
10-99 = 90 which is 180
100-200 = 100 which is 300 digits
9+180= 189
1392-189= 1203
1200÷300=400 which 1200 digits
401 is the 1392 number scanned

2x - 5 = 1
Add 5 to both sides;
2x = 6
Divide both sides by 2;
x = 3
