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:

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

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

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

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

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