A multi-step algebra equation requires expanding expressions and isolating the variable carefully.
Solve:
\[ 3(x+4)-5=16 \]
Solution:
\[ \text{Expand brackets:} \] \[ 3x+12-5=16 \] \[ \text{Simplify:} \] \[ 3x+7=16 \] \[ \text{Subtract 7:} \] \[ 3x=9 \] \[ \text{Divide by 3:} \] \[ x=3 \]
The variable is isolated through systematic steps.
