Explanation:
on the right side of the equation we can add like terms, meaning adding the x terms with the x terms(that means including their coefficients, in this case that x has a 2 in front of it), and the normal numbers with the other normal numbers. So by simplifying the right side of the equation with the x terms first we have
x+2x=3x
and
5+2=7
Thus we get
3x+7
Answer:
3x+7 is equal to x+5+2x+2
You can add x and 2x (x+2x) to get 3x
Then you can add 5 and 2 (5+2) to get 7
Therefore 3x+7 is equal to x+5+2x+2
