Answer :
Certainly! Here is the detailed step-by-step solution along with the justifications for each step:
1. Apply the Segment Addition Postulate:
- Original Equation: [tex]\( 7x - 3 = (2x + 6) + (3x - 3) \)[/tex]
- Justification: Segment Addition Postulate
2. Simplify the right side:
- Simplified Equation: [tex]\( 7x - 3 = 5x + 3 \)[/tex]
- Justification: Simplify
3. Subtract [tex]\( 5x \)[/tex] from both sides:
- Equation after Subtraction: [tex]\( 7x - 5x - 3 = 5x - 5x + 3 \)[/tex]
- Simplified: [tex]\( 2x - 3 = 3 \)[/tex]
- Justification: Subtraction Property of Equality
4.Add 3 to both sides:
- Equation after Addition: [tex]\( 2x - 3 + 3 = 3 + 3 \)[/tex]
- Simplified: [tex]\( 2x = 6 \)[/tex]
- Justification: Addition Property of Equality
5. Divide both sides by 2:
- Equation after Division: [tex]\( 2x / 2 = 6 / 2 \)[/tex]
- Simplified: [tex]\( x = 3 \)[/tex]
- Justification: Division Property of Equality
Summary of steps with justifications:
