2. Multiple the second one by 2
2x+4y=22
4x-4y=-16
6x = 6, x = 1

3. Add them together
8x = 24, x = 3

In 2, we are asked to solve the systems of equations to solve for the variables using elimination. 
 3x + 3y = 27-3(x - 3y = -11)      12 y  = 60        y = 5        x = 4
 2x + 4y = 22 2x - 2y = -8     6y  = 30     y   = 5     x   = 1
  5x - y = 0  3x  + y = 24  8x    =  24   x = 3   y = 15

Insert one term between -13 and -119 to create an arithmetic sequence of three terms.
daser333 [38]

Answer:

-66

Step-by-step explanation:

- 13, ____, -119

first, find the common difference:

-13 - (-119) = 106

next, divide 106 by 2: \frac{106}{2} = 53

so, the common difference is 53.

now, subtract 53 from -13:

-13 - 53 = -66
