2 + X = 9 - 4 - 2X
X + 2X = 9 - 4 - 2 (moving the X's to one side and the numbers to the other)
3X = 3 (combining like terms)
X=1 (dividing both sides by 3)
Check:
2+1 = 9 - 4 -2(1)
3 = 3

(-2, 4)
2x-4
5x+2=2x-10 x=-4
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
