Question

what is elimination method give example​

Answer 1

Step-by-step explanation:

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:

3x+2y=5 -1

4×-2y=9 -2

7x=14

x=2

put x value in -1

3x+2y=5

3×2+2y=5

6-5=2y

1=2y

y=2
