What is -4x-5=6-11x? Please show work

First, you would add 11x to both sides, because you are trying to separate the variable pieces and the constants (integers).

If performed correctly, you would get the equation
7x-5=6

Then, you would add 5 to both sides, to get the 7x alone.

This results in the equation 7x=11

Then, to get x alone, without a coefficient, you would need to divide both sides by 7.

x=11/7

Select the correct answer.<br> What is the solution to the equation?

Ierofanga [76]

Answer:

B

Step-by-step explanation:

$\sqrt{x}$ + 6 = x ( subtract 6 from both sides )

$\sqrt{x}$ = x - 6 ( square both sides )

x = (x - 6)² ← expand using FOIL

x = x² - 12x + 36 ( subtract x from both sides )

0 = x² - 13x + 36 , that is

x² - 13x + 36 = 0 ← in standard form

(x - 4)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 9 = 0 ⇒ x = 9

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

x = 4

left side = $\sqrt{4}$ + 6 = 2 + 6 = 8

right side = x = 4

Since 8 ≠ 4 then x = 4 is an extraneous solution

x = 9

left side = $\sqrt{9}$ + 6 = 3 + 6 = 9

right side = x = 9

Thus the solution is x = 9 → B
