Question

what is the value of $x$?
$x + 7 = 11$
$ - 7 - 7$
$ x = \boxed{?}$
subtract 7 on both sides.

Explanation:

Step1: Subtract 7 from both sides

We have the equation \( x + 7 = 11 \). To isolate \( x \), we subtract 7 from both sides of the equation. Mathematically, this is done as follows:
\( x + 7 - 7 = 11 - 7 \)

Step2: Simplify both sides

Simplifying the left - hand side, \( x+7 - 7=x \) (because 7 - 7 = 0). Simplifying the right - hand side, \( 11-7 = 4 \). So we get \( x = 4 \).
