X + 2x + 12y + x Apply the properties of operations by combining like terms to produce an equivalent expression. Prove your answer by showing your work.

4(x+3y)

Step-by-step explanation:

Given the expression X + 2x + 12y + x

First thing to do is combine the like terms;

X + 2x + 12y + x

= x+x+2x+12y

Add the like terms(Addition property)

= 4x + 12y

Then factor out the like terms

= 4(x+3y)

Hence the equivalent expression is 4(x+3y)
