Answer:
Step-by-step explanation:
There are some errors in your table. Column 1, for example, should be all odd numbers. Columns should alternate even/odd.
It can be useful to build a spreadsheet that fills these numbers.
5 times 19-13 would equal 30 as 19-13 is 6 times 5 =30
One-half of a number plus six will equal 20.
Solving:
1/2x + 6 = 20
-6 -6
1/2x = 14
*2/1 *2/1
x = 28 <--Answer to problem
