0.4(5x-12)+0.5x=15.2

We move all terms to the left:

0.4(5x-12)+0.5x-(15.2)=0

We add all the numbers together, and all the variables

0.5x+0.4(5x-12)-15.2=0

We multiply parentheses

0.5x+2x-4.8-15.2=0

We add all the numbers together, and all the variables

2.5x-20=0

We move all terms containing x to the left, all other terms to the right

2.5x=20

x=20/2.5

x=8

How to find all real solutions
AlladinOne [14]
\bf \sqrt{\sqrt{x-5}+x}=5\leftarrow \textit{squaring both sides}&#10;\\\\&#10;\sqrt{x-5}+x=25\implies \sqrt{x-5}=25-x\leftarrow \textit{squaring both sides}&#10;\\\\&#10;x-5=(25-x)^2\implies x-5=625-50x+x^2&#10;\\\\&#10;0=x^2-51x+630\implies 0=(x-30)(x-21)

and surely you'd know what the roots are
