forGiven the equation shown in the picture, you know that its solution is:
[tex]x=6[/tex]
Therefore, you know that the value on the left side is:
[tex]\begin{gathered} =6((6)+4) \\ =6(10) \\ =60 \end{gathered}[/tex]
If you substitute the value of "x" into the part of the expression that is not covered by the ink, you get:
[tex]\begin{gathered} =6\mleft(6+7\mright) \\ =6(13) \\ =78 \end{gathered}[/tex]
Therefore, in order to both parts to be equal to 60, the number covered by the ink must be 18 or the expression covered by the ink must have a value of 18, because:
[tex]78-18=60[/tex]
Hence, the answer is: Fourth option.
