OK so to solve this we will subtract 16x from 2x to get -14x
-14x - 4y + 3x^2 + 7y
add - 4y and 7y to get 3y
-14x + 3x^2 +3y
and then to simplify we are going to move the -14x
3x^2 +3y - 14x

First:

Subtract 5 on each side of the equals sign to cancel it out. You should get 13x=144.

Next:

Divide 13 from each side of the equals sign to get x by itself.

Answer:

X=11.0769230769. You may need to round it up to 11.08 or 11.1 depending on how your teacher normally has you answer

Answer:

d = 7 + 3\sqrt{3} and

d = 7 - 3\sqrt{3}

Step-by-step explanation:

To solve the equation, d^2 - 14d - 22 = 0, using the quadratic formula,

Recall: quadratic formula = \frac{-b ± \sqrt{b^2 - 4ac}}{2a}

Where,

a = 1

b = -14

c = 22

Plug in your values into the formula and solve:

\frac{-(-14) ± \sqrt{(-14)^2 - 4(1)(22)}}{2(1)}

\frac{14 ± \sqrt{196 - 88}}{2}

\frac{14 ± \sqrt{108}}{2}

d = \frac{14 + \sqrt{108}}{2}

d = \frac{14 + 6\sqrt{3}}{2}

d = (\frac{2(7 + 3\sqrt{3})}{2}

d = 7 + 3\sqrt{3}

And

d = \frac{14 - \sqrt{108}}{2}

d = \frac{14 - 6\sqrt{3}}{2}

d = (\frac{2(7 - 3\sqrt{3})}{2}

d = 7 - 3\sqrt{3}
