Question

elimination metad examples​

Answer 1

Answer:

Example

Use elimination to solve the system. 2x + y = 12 −3x + y = 2

2x + y = 12 3x – y = −2 5x = 10 Rewrite the second equation as its opposite. Add.

x = 2 Solve for x.

2(2) + y = 12 4 + y = 12 y = 8 Substitute y = 2 into one of the original equations and solve for y.

Answer 2

Step-by-step explanation:

elimination method example

x+y=2

x-y=3

x+y=2

x-y=3

- + -

_____

0+2y= -1

y = -1/2

x+y=2

x -1/2 = 2

2x -1 = 4

2x = 5

x = 5/2
