x=5.
10x-4x (6x) +10-6x (=10) If 10 is 2x, x=5.
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
4x+6x=30 is the same as: 10x=30 so we divide by 10 and get: x=3 (I do not see how this relates to calculus, but O.K.)
8x-2x+4x=10x
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
10x + 17 = 4x - 16x = -18x = -3
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
4x - 5 + 2x = 37
It is 2(2x+3) when factorised
They are: (4x-5)(2x+5)
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
