Evaluate algebraic expressions correctly using substitution and order of operations.
Turn an algebraic expression into arithmetic form
Problem
Substitute \(x~=~-4\) into \(2x~-~3\) and evaluate. Report the numerical substitution equation and result.
Big Picture
What this problem is really about
Keep the negative replacement intact by writing it in parentheses wherever x appears. The coefficient still means multiplication, so evaluate that signed product before carrying out the subtraction. Report the complete numerical substitution equation as well as its result, making the preserved negative sign visible.
