5x- 4 = 5(x- 3) + 11 \\ 5x - 4 = 5x - 15 + 11 \\ 5x -5x = 4 - 15 + 11 \\ 0=0
x = Real numbers

Rearrange:rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*x-4-(5*(x-3)+11)=0
Step 1 :Simplify 5x-4 - 5x-4 Pulling out like terms : 1.1 Pull out 5x-4

After pulling out, we are left with :
(5x-4) • ( 1 +( (-1) ))
Equation at the end of step 1 : 0 = 0 step 2 :
Solve 0 = 0 Equations which are always true : 2.1 Solve 0 = 0This equation is a tautology (Something which is always true)
