Given,
The expression is: x - 7 = 4.
Required:
The number required to add both sides to get the value of x.
Taking the expression as,
[tex]x-7=4[/tex]To get the value of x, by adding 7 to both sides.
[tex]\begin{gathered} x-7+7=4+7 \\ x=11 \end{gathered}[/tex]Hence, the 7 should be added to both sides of the following equation to solve for x.
