4x plus 6 equals 6x - 12?
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
2x plus 5 equals 7-4x?
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
Are the two equations -6 plus y equals 2x and 2y-4x equals 12 dependent?
In standard form, -6 + y = 2x is 2x - y + 6 = 02y - 4x = 12 is 4x - 2y + 12 = 0Each coefficient of the second is twice the corresponding coefficient of the first. So the equations are the same (and therefore dependent).In standard form, -6 + y = 2x is 2x - y + 6 = 02y - 4x = 12 is 4x - 2y + 12 = 0Each coefficient of the second is twice the corresponding coefficient of the first.

What is the answer to 10x - 4x plus 5 x 2 - 6 x equals -2x?
x=5. 10x-4x (6x) +10-6x (=10) If 10 is 2x, x=5.
8x plus 30 equals 4x plus 18 solve for x?
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
