x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333
one is y=3x+3 so is y=3x+5
Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.
