3x - x + 4 = 0
Need Step by Step PLZ

3x - x + 4 = 0

2x = -4

x = -4 ÷ 2

x = -2

x = {0, 4}

Step-by-step explanation:Simplifying

3x(x + -4) = 0

Reorder the terms:

3x(-4 + x) = 0

(-4 * 3x + x * 3x) = 0

(-12x + 3x2) = 0

Solving

-12x + 3x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '3x'.

3x(-4 + x) = 0

Ignore the factor 3.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve:

Simplifying

x = 0

Solving

x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying

x = 0

Subproblem 2

Set the factor '(-4 + x)' equal to zero and attempt to solve:

Simplifying

-4 + x = 0

Solving

-4 + x = 0

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + x = 0 + 4

Combine like terms: -4 + 4 = 0

0 + x = 0 + 4

x = 0 + 4

Combine like terms: 0 + 4 = 4

x = 4

Simplifying

x = 4

Solution

x = {0, 4}

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
