4x-1 = 6x-15 4x-6x = 1-15 -2x = -14 x = 7
8x-1=23-4x 12x=24 x=2
-1-2x-4x=19-6x-1 = -19x = 3
4x - 1 = 9(+ 1 on both sides)4x = 10(Divide both sides by 4)x = 2.5
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
How do you solve y=-4x+1
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1

16x³ - x = 0 By factorization, we obtain: x(16x² - 1) = 0 x(4x - 1)(4x + 1) = 0 Set each term by 0 and solve for x to get: x = 0 and 4x - 1 = 0 and 4x + 1 = 0 x = {0, ±¼}
Subtract 4x from each side getting 1 = 48x so x = one forty-eighth
4x = 72.divide both sides by 4x = 18
