Answer:

Given:


\sf 0.25x+2x+12=39

Add the like terms:


\sf 2.25x+12 =39

Subtract 12 from both sides:


\sf 2.25x +12-12=39-12


\sf 2.25x =27

Multiply both sides by 100:


\sf 2.25x* 100=27* 100


\sf 225x=2700

Divide both sides by 225.


\sf (225x)/(225)=(2700)/(225)


\sf x= 12

So, the final answer is:


\sf 0.25x+2x+12=39 \longrightarrow \boxed{ \textsf{Given}}


\sf 2.25x +12=39 \longrightarrow \boxed{ \textsf{ Addition Property of Equality}}


\sf 2.25x=27\longrightarrow \boxed{ \textsf{ Subtraction Property of Equality}}


\sf 225x=2700 \longrightarrow \boxed{ \textsf{Multiplication Property of Equality}}


\sf x=12 \longrightarrow \boxed{ \textsf{Division Property of Equality}}
