6x-10=x
you subtract 6x on both sides...
6x-6x-10=x-6x
you are left with...
0-10 or -10=-5x
then divide both sides by -5...
-10/-5=-5x/-5
to get...
2=x
finally, check your answer.
6x2-10=2
6x2=12
12-10=2
-10 = 6x - 16, or 16 - 10 = 6x, or x = 1.
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
x = 10
6x + 10 = 72 6x = 72 - 10 x = 62/6 x = 10.3333
x=10
10
If 6x + 10 = 11x , then x=2.
8x+2 = 6x-10 8x-6x = -2-10 2x = -12 x = -12/2 X= -6
you just only need the first 2 parts of the equation! 6x-10=10x so you have to minus 6x each side: so 6x-6x-10=10x-6x, so it turns to -10=4x. Then you have to divide -10 by 4. so -10/4=-2.5 so x is -2.5.
x2+6x-40 = 0 (x+10)(x-4) = 0 x = 4 or x = -10
8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.
-20 = -4x - 6x -20 = -10x -20 / -10 = -10x / -10 2 = x x = 2
