Value of n is 7
Step-by-step explanation:
-6(2n - 7) + 2(n - 4) = -36
-12n + 42 + 2n - 8 = -36
-10n + 34 = -36
-10n = -70
⇒ n = 7
Answer:

Answer:
(3, 6); (-3, 18)
Step-by-step explanation:
We equate the 2 expressions in x :-
x^2 - 2x + 3 = -2x + 12
x^2 - 2x + 2x + 3 - 12 = 0
x^2 - 9 = 0
(x - 3)(x + 3) = 0
So x = 3 or -3.
When x = 3, f(x) = -2(3) + 12 = 6.
When x = -3, f(x) = -2(-3) + 12 = 18.
