Answer:
(-3, -2)

Explanation:
-Solve the equation for x-
3x -8y = 7
x= -7 -2y
-Substitute the given value of x into the equation 3x -8y =7
3(-7 -2y) -8y =7
-Solve the equation for y-
y= -2
-Substitute the given value of y into the equation x= -7 -2y
x= -7 -2 x (-2)
-Solve the equation for x
x= -3
-The possible solution of the system is the ordered pair (x, y)
(x, y) = (-3, -2)

Answer:

[tex]\displaystyle [-3, -2][/tex]

Step-by-step explanation:

{3x - 8y = 7

{x + 2y = −7

−⅓[3x - 8y = 7]

{−x + 2⅔y = −2⅓ >> New Equation

{x + 2y = −7

_____________

[tex]\displaystyle \frac{4\frac{2}{3}y}{4\frac{2}{3}} = \frac{-9\frac{1}{3}}{4\frac{2}{3}}[/tex]

[tex]\displaystyle -2 = y[/tex][Plug this back into both equations above to get the x-coordinate of −3]; [tex]\displaystyle -3 = x[/tex]
