Question

|3) |x + 5| = 11 ,4 .​

Answer 1

Ответ:

(×+5)=11,4

×=11,4 - 5 = 11.9

×=11.9

Answer 2

It seems like you have an equation involving the absolute value of a variable, x. The equation is:

| x + 5 | = 11

To solve this equation, you can consider two cases, one for when the expression inside the absolute value is positive, and the other when it's negative.

Case 1: x + 5 is positive (x + 5 > 0): In this case, you don't need to change the absolute value. So, you have:

x + 5 = 11

Now, subtract 5 from both sides to solve for x:

x = 11 - 5 x = 6

Case 2: x + 5 is negative (x + 5 < 0): In this case, you need to negate the expression inside the absolute value by multiplying it by -1. So, you have:

-(x + 5) = 11

Now, distribute the negative sign:

-x - 5 = 11

Add 5 to both sides:

-x = 11 + 5 -x = 16

Now, multiply both sides by -1 to solve for x:

x = -16

So, the solutions to the equation |x + 5| = 11 are x = 6 and x = -16.
