120 + 5d = 445 <==
** parts + labor = 445
p = 120
labor = 5 hrs * d...where d is cost per hr

Answer: 3y = 2(x - 5)--------------------------------------------------------
<span>-49 + -2x + 12x = 101 + -12x + 12x Combine like terms: -2x + 12x = 10x -49 + 10x ... 101 + 49 = 150 10x = 150 Divide each side by '10'. x = 15 Simplifying x = 15 </span><span>

according to the code of Mathematical Logic, there exists more properties, one of its principles is the consequence and effects property, or the so-called equivalence implicationwhich is defined as follows:Two expressions A and B are equivalent if A can produce B, and B can produce A. It means A implies B and B implies A.</span>
