Solve the equation. 5x + 8 - 3x = -10.
x = -9, x = -1, x = 1, x = 9

Solution:

Linear equations are nothing but yet another subset of "equations". Any linear calculations requiring more than one variable can be done with the help of linear equations. 

The standard form of a linear equation in one variable is of the form ax + b = 0. 

Here, x is a variable, and a and b are constants.

Given equation is:

5x + 8 - 3x = -10

Separating the like terms

⇒ 5x - 3x = -10 - 8

⇒ 2x = -18

⇒ x = (-18/2)

⇒ x = -9

Hence the required value of x is -9.

Solve the equation. 5x + 8 - 3x = - 10.

Summary:

The only value of x satisfying the linear equation of order 1 is x = -9. A linear equation in one variable is an equation which has a maximum of one variable of order 1.
