Hi,

 x + (x+2) + (x+4) = 75, 3x = 69, x = 23  |||   23, 25, 27 the 3 consecutive odd integers

"PEMDAS", "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

2(4x-3)-8=4+2x

 8x - 6 - 8 = 4 + 2x,  6x = 18,  x = 18/6  0r  x = 3

2/3(3x+18)=5x-9 

  2x + 12 = 5x - 3,  15 = 3x,  x = 5
