4x^5 divided by 6x^3
Vitek1552 [10]

Answer:

4.74

Solution for 6x+3=4x+5 equation:

Simplifying

6x + 3 = 4x + 5

Reorder the terms:

3 + 6x = 4x + 5

Reorder the terms:

3 + 6x = 5 + 4x

Solving

3 + 6x = 5 + 4x

Solving for variable 'x'.

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

Add '-4x' to each side of the equation.

3 + 6x + -4x = 5 + 4x + -4x

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

3 + 2x = 5 + 4x + -4x

Combine like terms: 4x + -4x = 0

3 + 2x = 5 + 0

3 + 2x = 5

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

3 + -3 + 2x = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2x = 5 + -3

2x = 5 + -3

Combine like terms: 5 + -3 = 2

2x = 2

Divide each side by '2'.

x = 1

Simplifying

x = 1
