Whats the rest of the question
Answer:

Step-by-step explanation:
The polynomial given for simplification is:

Now, we combine like terms using the commutative property of addition.
The commutative property of addition states that:

So, the order can be shuffled when we add terms.
The terms containing 't' are grouped together and the constant terms are grouped together. This gives,

Now, we group them using associative property and converse of distributive property as:

Simplifying the above expression, we get:

Therefore, the simplified form is 
Answer:
Multiply by 3 -> 3(x - y = 6)
Step-by-step explanation:
Cuz since the 2nd is positive 3y
u need a negative 3y to get rid of it
3(x - y = 6)
2x + 3y = 7
3x - 3y = 18
2x + 3y = 7
5x/5 = 25/5
x = 5
5 - y = 6
-5 -5
-y/-1= 1/-1
y = -1
(5,-1)
The answer is 28 because 1/4 is equivalent to .25 so 3.25 x 24 equals 28.
