Answer:

x= 9 y=2

Step-by-step explanation:

Add up the equations vertically to eliminate y.

-x=-9

change the signs:

x=9

substitute the given value of x into the equation 2x-4y=10

2(9)-4y=10

18-4y=10

4y=8

y=2

11,20,29, Find the 30th term.
Mekhanik [1.2K]

Answer:

372

There are already 3 terms. So, now you have to find the 30th term.

The difference of 30 - 3 is 27. Now, since you add 9 for every term, multiply it by 27.

27 x 9 = 243.

The third term is 29. So you add 29.

Your answer will be 372. Hope it helps.
