5x plus 3 does equal 3 plus 5x; commutative law.
X=-3
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4

5x plus 3 does equal 3 plus 5x; commutative law.
X=-3
x would equal 1, 8x=5x+3, then you minus 5x from both sides, 3x=5x+3, then you divide 3 from both sides, x=1.
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
33
5x+3 = -17 5x = -17-3 5x = -20 x = -4
5x + 3 = -12 5x =-12-3 =-15 x = -3
5x² - 18x + 9 = (5x² - 15x) - (3x - 9) = 5x(x - 3) - 3(x - 3) = (5x - 3)(x - 3).
5x - 4x = 13 - 3 ie x = 10
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
-4x + 3 = -5x + 3add 5x to each sidex + 3 = 3subtract three from each sidex = 0
