SOLUTION: State the property of real numbers or the property of equality that justifies each step in the solution of the equation given. 3x + 5 = 8 x 3x + 5 + (�3x) = 8x + (�3x) 3

Question 902755: State the property of real numbers or the property of equality that justifies each step in the solution of the equation given.
3x + 5 = 8 x
3x + 5 + (�3x) = 8x + (�3x)
3x + [(�3x) + 5] = 8x + (�3x)
[3 x + (�3x)] + 5 = 8x + (�3x)
0 + 5 = 8x + (�3x)
5 = 8x + (�3x)
5 = [8 + (�3)]x
5 = 5 � x
15 � 5 = 15 (5x)
15 � 5 = (15 ∙5)x
1 = 1 � x
1 = x
x = 1
