System of equations.</h3>
Put (1) to (2):
Substitute the value of x to (1):
Solution:
Answer: x-3y+21=0
Step-by-step explanation:
move the constant to the left then divide both sides then booom
Notice the following pattern:
2 - 0 = 2
6 - 2 = 4
12 - 6 = 6
20 - 12 = 8
It's reasonable to assume that consecutive terms in the sequence differ by increasing multiples of 2, so that for the next number (call it x) we expect to see
x - 20 = 10 ==> x = 30
and for the number after that (call it y) we would see
y - x = y - 30 = 12 ==> y = 42
C would be the right answer
