Hello there.
<span>Solve -2x+5y-9 when y=
Just c</span><span>ombine like terms
and you'll get
</span>=<span><span>−<span>2x</span></span>−<span>3</span></span>
Answer:
7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.
On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.
For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.
