Answer:
(0, -4)
Step-by-step explanation:
The solution to the system is the point that is on both lines. It is where the lines intersect (cross). They intersect at the point (0, -4)
Subtract 27 and you can get a relationship between b and c. Without additional information, that's the best you can do.
3b +c = -43
Answer:
2×6729=13458
Step-by-step explanation:
Answer: a = 
Step-by-step explanation:
Rewrite the equation as 4a + 9ab=K
Factor out a of 4a + 9b
a (4 + 9b) = K
divide each term by 4 + 9b and simplify
=
Y = mx + b is the slope intersect form.
so 8x - 7y = 23
-7y = -8x + 23
y = -8x/-7 + 23/-7
y = 8/7x - 23/7 Ans
