Each variable that doesn’t have a number in front of it is an invisible 1. Since y, y, and y are like terms because they have the same exponent and variable. Because they are like terms you can add and subtract them. So 1y+1y+1y= 3y
Answer: 3/10
Step-by-step explanation: Since our denominators of 2 and 5have no
factors in common, our least common denominator is 2 · 5 or 10.
In order to get a denominator of 10 in each fraction,
we multiply top and bottom of the first fraction by 5
and top and bottom of the second fraction by 2.
That gives us 5/10 - 2/10 which is 3/10.
