i advise you do your own homework but....
3-x=2
take away 3 from both sides
-x=-1
divide both sides by -1
x=1
and there's your answer:)
another way:
2 plus what equals three
did you go to school today? were you listening to the teacher? maybe its better to ask the teacher questions rather than going home confused
3x + 2 = 3x + 6 This is not possible.
3x + 2 = 0 3x = -2 x = -2/3
3x - 7 = 2 3x = 9 x = 3
3x+12 = 18 3x = 18-12 3x = 6 x = 2
3x + 2 = -10 3x = -12 x = -4
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
x + 2 = 3x-1 -2x = -3x = 1,5
3x + 2 = Y
x2 - 3x + 2 = 0
-1
(2, -1)
