The number should be 54, where we can add 36 to get twice the number decreased by 18.
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation.
Given that, when we add 36 with a number then it gives twice the number decreased by 18.
Let the number be [tex]x[/tex] .
We get the linear equation
[tex]x+36=2x-18\\\Rightarrow x-2x=-18-36\\\Rightarrow -x=-54\\\Rightarrow x=54[/tex]
Therefore, the number should be 54.
