Answer:
Added Like Terms: 20y + 5
Equivalent Expression: 12y + 8y + 4 + 1
Explained:
Add like terms. Both <em>6y</em> and <em>14y</em> have a variable of y, so they can be added.
6y + 14y = 20y
Next, add the next set of like terms. <em>2</em> and <em>3</em> both don't have a variable, so you can add em'.
2 + 3 = 5
There are no more like terms to add since 20y has a variable and 5 doesn't, leaving you with the answer 20y + 5.
As for the equivalent expression, I just created another expression that equals 20y + 5.
