What is the solution to the following system of equations? x+y=5

marta [7]

Answer:

(3,2)

Step-by-step explanation:

Let's solve this via elimination method:

$\begin{cases} x+y=5\\x-y=1\end{cases}$

By subtracting equation 2 from equation one we obtain:

$\begin{cases} x+y=5\\-(x-y=1)\end{cases}\\\\0x+2y=4\\\\y=2$

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

$x+y=5\\\\x+2=5\\x=5-2\\\\x=3$

Therefore the solution for the system of equations is:

x=3 and y = 2 as an ordered pair we have (3,2)

Sergio039 [100]

Answer:

The answer is (-3,7/2)

Step-by-step explanation:

$2 {x}^{2} - x - 21 = 0 \\ (2x - 7)(x + 3) = 0 \\ 2x - 7 = 0 \: \: \: or \: \: x + 3 = 0 \\ x = \frac{7}{2} \: \: and \: x = - 3$
