Пошаговое объяснение:

х>0

-3/4х+18,25= - 2.

-3/4х=-20,25.

х₁= (-20,25/ - 3)*4=15,1875≈15,2

х<0.

3/4х=-20,25.

х₂=-15,1875≈ - 15,2.

Answer 2

To solve the equation, we need to isolate the variable x. Let's proceed step by step:

Step 1: Get rid of the constant term on the right side by subtracting 18.25 from both sides of the equation:

-3/4 * |x| + 18.25 - 18.25 = -2

Step 2: Simplify the left side of the equation:

-3/4 * |x| = -2

Step 3: Divide both sides by -3/4:

|x| = -2 / (-3/4)

Step 4: Divide -2 by -3/4:

|x| = 8/3

Step 5: Since the absolute value of a number is always non-negative, we can rewrite the equation as two separate equations:

x = 8/3 (when x is positive)

x = -8/3 (when x is negative)

So the solutions for the equation are x = 8/3 and x = -8/3.
