Question

Can you help me on the question

Answer 1

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 2

Answer:

$\displaystyle [-3, -2]$

Step-by-step explanation:

{3x - 8y = 7

{x + 2y = −7

−⅓[3x - 8y = 7]

{−x + 2⅔y = −2⅓ >> New Equation

{x + 2y = −7

_____________

$\displaystyle \frac{4\frac{2}{3}y}{4\frac{2}{3}} = \frac{-9\frac{1}{3}}{4\frac{2}{3}}$

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