2x - y = 5
x + y = 2
solve the system of equations.
(17, -15)
(17/8, -1/8)
to solution
no solution

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

idk

step-by-step explanation:

thats not a system of equations, that is a solution

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
