\displaystyle\Rightarrow{x}={8} Explanation: We start with \displaystyle{11}{x}+{\left(-{4}{x}\right)}={56} Adding a negative is equivalent to subtraction \displaystyle{11}{x}-{4}{x}={56} ...

Suppose x is non-negative, else consider -x. Suppose |ax-bx|=a, else we can swap over the roles of a and b. Let us vary b. It is clear that a is non-negative and is a multiple of x. In ...

11x-5=9x+7 One solution was found :                   x = 6 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : ...

Surely, for a function f(x) = K + ax the iteration has a tractable form. Often the iteration is written as f°^h(x) where the tiny circle indicates that the superscripted h means the ...

-11x+44=121 One solution was found :                   x = -7 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : ...

-1x+-1=x+1 One solution was found :                   x = -1 Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : ...
