Sagot :
Answer:
(-3, -4)
Explanation:
The system of equations is:
y = -2x - 10
y = 2x + 2
So, we can replace y by (-2x - 10) on the second equation as follows:
y = 2x + 2
-2x - 10 = 2x + 2
Then, we can solve for x:
-2x - 10 = 2x + 2
-2x - 10 + 2x = 2x + 2 + 2x
-10 = 4x + 2
-10 - 2 = 4x + 2 - 2
-12 = 4x
-12/4 = 4x/4
-3 = x
Finally, we can replace x by -3 on the first equation and get:
y = -2x - 10
y = -2(-3) - 10
y = 6 - 10
y = -4
So, the solution is the ordered pair (x, y) = (-3, -4)
