3x plus 10x - 7
With out knowing what ' x ' actually is.. it will reduce down to.
3x + 10 x - 7
=
13x - 7
5x+8x+3x-2x = 14x
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
(3x-2)(x-2)
It is: 8-2x
-3x + 5 = 20 -3x = 15 x = -5
23
x=7
x=8
x = -8
3
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
