Answer:

Step-by-step explanation:

hello :

x²-48 =1

x²-48-1 =1-1

x²-49=0 means : x²-7²=0

by identity : a²-b²= (a-b)(a+b)

by factoring: (x-7)(x+7)=0

x-7=0 or x+7=0

x=7 or x= -7

How do you solve 8|x+2|-6=5|x+2|+3

sergejj [24]

Answer:

x = 1 or x = -5

Step-by-step explanation:

Solve for x over the integers:

8 abs(x + 2) - 6 = 5 abs(x + 2) + 3

Subtract 5 abs(x + 2) - 6 from both sides:

3 abs(x + 2) = 9

Divide both sides by 3:

abs(x + 2) = 3

Split the equation into two possible cases:

x + 2 = 3 or x + 2 = -3

Subtract 2 from both sides:

x = 1 or x + 2 = -3

Subtract 2 from both sides:

Answer: x = 1 or x = -5

The answer is B. The values of y must only be positive because it is equal to
$| - x|$
The other options states that the values of y could be negative which is why it is wrong.
