How many real solutions does this system of equations have? x2+y2=363x−y+1=0 A. 0 B. 3 C. 2 D. 1

Correct option: C -> 2

Step-by-step explanation:

The first equation is:

And the second equation is:

From the second equation, we have:

Using this value of y in the first equation, we have:

Calculating the discriminant Delta, we have:

We have , so we have two real values for x, therefore we have two solutions for this system.

Correct option: C.

(If the system of equation is actually:

We would have:

We also have , so we have two solutions for this system.

Correct option: C.)

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
