X1=-26 ; X2=26........

Answer 2

To solve for the values of x in the equation -1/4 * |x| + 3.5 = -3x, we can follow these steps:

1. Subtract 3.5 from both sides of the equation: -1/4 * |x| = -3x - 3.5

2. Divide both sides of the equation by -1/4: |x| = (3x + 3.5) / (1/4)

3. Remove the absolute value by considering two cases: positive and negative values of x.

Case 1: x is positive x = (3x + 3.5) / (1/4)

Multiply both sides by 4 to get rid of the fraction: 4x = 12x + 14

Subtract 12x from both sides: -8x = 14

Divide by -8: x = -14/8 x = -7/4

Case 2: x is negative x = -(3x + 3.5) / (1/4)

Multiply both sides by 4 to get rid of the fraction: 4x = -12x - 14

Add 12x to both sides: 16x = -14

Divide by 16: x = -14/16 x = -7/8

So, the solutions for the equation are: x1 = -7/4 (or -1.75) x2 = -7/8 (or -0.875)
