Given:
The expression is
[tex]\dfrac{\_\_\_+4}{2}=10[/tex]
To find:
The number of the blank.
Solution:
Let x be the missing number for the blank. Then,
[tex]\dfrac{x+4}{2}=10[/tex]
Multiply both sides by 2.
[tex]x+4=20[/tex]
Subtract 4 from both sides.
[tex]x=20-4[/tex]
[tex]x=16[/tex]
Therefore, the missing number for the blank is 16.
