Algebra extra points!
solve the system using elimination.
52 + 4y = 12
3.1 - 3y = 18
in

52+4y=12

We move all terms to the left:

52+4y-(12)=0

We add all the numbers together, and all the variables

4y+40=0

We move all terms containing y to the left, all other terms to the right

4y=-40

y=-40/4

y=-10

3.1-3y=18

We move all terms to the left:

3.1-3y-(18)=0

We add all the numbers together, and all the variables

-3y-14.9=0

We move all terms containing y to the left, all other terms to the right

-3y=14.9

y=14.9/-3

y=-4+2.9/3

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
