First we'll multiply the second equation by -2
Now let's add the new equation and the first one.
We found y's value. We'll plug it in one of the equations to find x's value.
Solution ;
(9, -6)
37.1
Hope this helps a lot!!
In simple words you just find what is being added to each term in order to get the next term. Subtracting 17 by 12 you get 5, 22 minus 17 is 5 as well. Now that what is being added is found, you go by the last term given which is 27. You keep adding 5 to the number until you get to the 22nd term which would result in 117. If you would want to know the equation in order for it to be plugged in then you would use f(x)= 7+5x . You would want to use this equation instead of f(x)= 12+5x because putting 1 as x would make it equal to 17 which is NOT the first term but the second.
Answer:
When N is an even number, use the first equation in the matrix. When N is negative use the second equation.
Step-by-step explanation:
n = 6 | 6/2 = 3
n=5 | 3(5)+1 = 16
Two twelfths that is the answer
