In order to find the value of x, you need to get it by itself.
subtract 8 from both sides:
x = 21
The value of x in x -8 = 13 is 21.
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the give question
We have
A linear equation in one variable, [tex]x-8 =13[/tex].
Solve the above linear equation for x
[tex]x - 8 = 13[/tex]
⇒[tex]x - 8 + 8 = 13+8[/tex] (adding 8 both the sides)
⇒[tex]x = 21[/tex]
Hence, the value of x in x -8 = 13 is 21.
