Let's solve by eliminating
x
. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
Add the two equations.
Divide by -11 to isolate
y
y= -2
Substitute
y
=
−
2
into either of the 2 equations, I'll just use the second one.
x = -1
You would want to go by reverse order of operations. This is a one step equation. You subtract 2 on both sides, in which you will get: -14 = k.
Answer:
-56 maybe
Step-by-step explanation:
-2*-7=14
8*-7= -56
1: 8 faces and 9 with the base 9 vertices and 16 edges
2: 3 faces and 5 with the bases 6 vertices and 9 edges
3: 3 faces and 4 with the base 4 vertices and 6 edges
Well if its exponential it must be x ^n
