3 + 5x is the simplest expression of this problem.
5x plus 3 does equal 3 plus 5x; commutative law.
5x-3 = 37 5x = 37+3 5x = 40 x = 8
5x-2x = 3

25x2+30x+9 25*9=225 15*15=225 15+15=3025x2+15x+15x+9[5*5xx 3*5x] [3*5x 3*3]5x(5x+3)+3(5x+3)(5x+3)(5x+3)Answer: (5x+3)2
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x-3 = 37 5x = 37+3 5x = 40 x = 8
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
steps: 3(5x-7) =(3)(5x-7) =(3)(5x)+(3)(-7) answer: 15x-21
5x + 3 = -12 5x =-12-3 =-15 x = -3
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
5x-2x = 3
