What is the solution to this system of equations using the linear combination method? 5x+y=2
4x+y=5

(im really bad at math so an explanation would be helpful so i can understand better)

Step-by-step explanation:

Subtracting both equations:

    5x + y = 2

 -  (4x + y = 5)

————————

1x + 0y = -3

x = -3

Substituting x = -3 for the second equation:

4(-3) + y = 5

Solving for y.

-12 + y = 5

y = 17

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
