Solve the following equation and check your result: 5x + 9 = 5 + 3x

Solution:

A mathematical equation that represents the relationship between two expressions on either side of the equal sign (=) is a Simple Equation. An equation consists of variables and numerical constants.

5x + 9 = 5 + 3x

Subtracting 3x from both sides,

5x - 3x + 9 = 5 + 3x - 3x

⇒ 2x + 9 = 5

Simplifying further,

2x = 5 - 9

⇒ 2x = - 4

⇒ x = - 4/2

Therefore, the value of x = - 2
