If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13
-8 + 7x = x - 506x = -42x = -6
x2 - 42x + 441 = (x - 21)2
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
x3 + 13x2 + 42x = x(x + 6)(x + 7).
if x-42x-8=0 x=-5.12500
If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13
y-42x = 24 >> Add 42x to both sides << y=24+42x >> Subtract 24 from both sides << y-24=42x >> Divine both sides by 42 << x=(y-24)/42
x = 8y = -42x - y = 2(8) - (-4) = 16 + 4 = 20
x = -8 already is a solution. If an equation has been changed until the value of x is found, and this value is accurate to the original equation, then the equation has been solved.
-8 + 7x = x - 506x = -42x = -6
x = -6
I can help you with that. To find the value of x in the equation 2x⅔ = 8, we can follow these steps: Cube both sides of the equation: This will get rid of the fractional exponent. (2x⅔)³ = 8³ Simplify the equation: 8x² = 512 Divide both sides by 8: x² = 64 Take the square root of both sides: √(x²) = √(64) Simplify to find x: x = ±8 Therefore, the solutions for x are 8 and -8.
x2 - 42x + 441 = (x - 21)2
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
x+2y=8 The x-intercept is the value of x when y=0, therefore substitute y=0 into the equation: x+0=8 therefore, x=8 The coordinates of this point is (8,0)
x3 + 13x2 + 42x = x(x + 6)(x + 7).
