Answer :
To solve for \( x \), you subtract 15 from both sides of the equation:
\[ 15 + x - 15 = 30 - 15 \]
This simplifies to:
\[ x = 15 \]
So, \( x = 15 \)
\[ 15 + x - 15 = 30 - 15 \]
This simplifies to:
\[ x = 15 \]
So, \( x = 15 \)
To solve the equation 15 + x = 30 for x, we need to isolate the variable x on one side of the equation.
To do that, we can subtract 15 from both sides of the equation:
15 + x - 15 = 30 - 15
This simplifies to:
x = 15
Therefore, x is equal to 15.
