Answer:

Step-by-step explanation:

here you go mate

step 1

x-6 = 5(x + 2) equation/Question

step 2

x-6 = 5(x + 2) simplify

x+(-)6=5x+10

x-6=5x+10

step 3

x-6=5x+10 subtract 5x

-4x-6=10

step 4

-4x-6=10 add 6

-4x=16

step 5

$\frac{-4x}{-4}=\frac{16}{-4} \\$

answer

x=-4

Hurry 50 points for correct answer

Ad libitum [116K]

Answer: "7 is a solution to the original equation. The value –1 is an extraneous solution."

Step-by-step explanation:

The equation $x=\sqrt{6x+7}$ can be solved by squaring both sides:

$x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0$

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

$1 = \sqrt{-1}\\ 7 = \sqrt{49}$

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is "7 is a solution to the original equation. The value –1 is an extraneous solution."
