Solve for x: 2 over 5 (x − 4) = 2x

An equation is a mathematical expression used to represent the equality between any two expressions.

Answer: For x: 2 over 5 (x − 4) = 2x, x = -1

Let us write the equation in the numeric form.

Explanation:

Mathematically, the equation will be written as:

(2/5) × (x−4) = 2x

2x - 8 = 10x

⇒ 2x - 10x = 8

⇒ -8x = 8

⇒ x = -1 

Hence for x: 2 over 5 (x − 4) = 2x, x = -1
