Which polynomial is equivalent to this expression if n≠-1n≠-1? 3+n−2n21+n?

Irina18 [472]

I suppose that the expression you wanted to write is $\frac{3+n-2n^2}{1+n}$ . If so, then we have:

$\frac{3+n-2n^2}{1+n}= \frac{3+3n-2n-2n^2}{1+n} \\ \\ = \frac{3(1+n)-2n(1+n)}{1+n} = \frac{(3-2n)(1+n)}{1+n} \\ \\ =3-2n$

What is the value of x in the solution to this system of equations? 3x = 2y + 14<br> y = -6x + 18

zmey [24]

Use substitution
3x = 2(-6x + 18) + 14
3x = -12x + 36 + 14
3x = -12x + 50
15x = 50, x = 50/15 = 10/3
Solution: x = 10/3
