Answer:

x= 16

x=1.5

Explanation:

Simplifying

3x + -0.5 = 0

Reorder the terms:

-0.5 + 3x = 0

Solving

-0.5 + 3x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.5' to each side of the equation.

-0.5 + 0.5 + 3x = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0

0.0 + 3x = 0 + 0.5

3x = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5

3x = 0.5

Divide each side by '3'.

x = 0.1666666667

Simplifying

x = 0.1666666667

Simplifying

2x + 3 = 0

Reorder the terms:

3 + 2x = 0

Solving

3 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 2x = 0 + -3

2x = 0 + -3

Combine like terms: 0 + -3 = -3

2x = -3

Divide each side by '2'.

x = -1.5

Simplifying

x = -1.5
