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
