We are given expression : mn – 11 mn + 3 .
<em>We need to find like terms in order to add or subtract the polynomials.</em>
Like terms are the terms those have same variables.
In the given polynomial, we have first term mn and second term -11mn.
Both of the terms has mn variables with them.
So, we can subtract mn - 11mn.
mn could be written as 1mn.
Therefore, 1mn -11mn = -10mn.
Answer:
x= -3
y= -2
From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.
