Answer 2

Answer:

Simplifying

4x + -5 = 6x + 5

Reorder the terms:

-5 + 4x = 6x + 5

Reorder the terms:

-5 + 4x = 5 + 6x

Solving

-5 + 4x = 5 + 6x

Solving for variable 'x'.

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

Add '-6x' to each side of the equation.

-5 + 4x + -6x = 5 + 6x + -6x

Combine like terms: 4x + -6x = -2x

-5 + -2x = 5 + 6x + -6x

Combine like terms: 6x + -6x = 0

-5 + -2x = 5 + 0

-5 + -2x = 5

Add '5' to each side of the equation.

-5 + 5 + -2x = 5 + 5

Combine like terms: -5 + 5 = 0

0 + -2x = 5 + 5

-2x = 5 + 5

Combine like terms: 5 + 5 = 10

-2x = 10

Divide each side by '-2'.

x = -5

Simplifying

x = -5
