Write a justification for Line 2, Line 3, and Line 4. Explain why you chose each justification.
Line 1      5x – 2 = 3x + 7
Line 2      2x – 2 = 7 
Line 3            2x = 9 
Line 4            x = 4.5  
 

Line 2: subtraction property (subtract 3x from each side)
Line 3: addition property. (add 2 to each side)
Line 4: division property (divide 2 from each side)

The measurement of angle S equals the measurement of angle R.

m∠S=m∠R
