Answer :
33
Explanation
Step 1
set the equation :
a) let
x represents the number you are thinking of
so
If I subtract 7 from it, the answer is 26, rewrite using math terms and the variable (x)
so
we need to subtract 7 from the number to obtain 26, hence
[tex]x-7=26[/tex]now, to solve for x , add 7 in both sides
[tex]\begin{gathered} x-7=26 \\ x-7+7=26+7 \\ x=33 \end{gathered}[/tex]therefore, the number is 33
