10x, 20x, 30x and so on.
2x, 4x, 6x, 8x, 10x, 12x
1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x and 10x
10x - 5x + 5x = 10x
If you mean: -10x+4-10x+5 then it is 9-20x when simplified
Y = 10x 10x = 40 y = 40
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
-10x-6 = -12 -10x = -12+6 -10x = -6 x = 3/5
Well usually a microscope comes with a lens that is 10x and with the lens on the bottom, it will multiply to make the microscope stronger
2-10x = -8
2x -10x = -8
10x-8 = 2
It is: -4x-10x = -14x
