Which equation results from adding the equations in this system?
eimsori [14]

Answer: 3x=3

Step-by-step explanation: Let's divide this into parts--

1. Adding the x variables: -2x+5x or 5x-2x = 3x.

2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)

3. Adding the numbers: 8-5 or -5+8 = 3.

Now just put it back into an equation: 3x + 0 = 3.

We don't need to add the 0, so the equation changes into 3x = 3.

Use the quadratic formula to solve the equation x^2-7x-6=0
olganol [36]

Answer:

\frac{7\pm\sqrt{73}} {2}

Explanation:

We have been given with the quadratic equation x^2-7x-6=0

We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

D=b^{2}-4ac

and after that to find the variable suppose x we have the formula

x=\frac{-b\pm\sqrt{D}} {2a}

And general quadratic equation is

ax^2+bx+c=0

On comparing the given quadratic equation with genral quadratic equation we will have values

a=1, b=-7 and c=-6

After substituting these values in the formula we will get  

D=(-7)^2-4(1)(-6)={73}

After substituting in the formula to find x we will get

\frac{-(-7)\pm\sqrt{73}} {2}= \frac{7\pm\sqrt{73}} {2}
