Question

Solve by elimination Method
32-4 = 21
6x+3y=9​

Answer 1

Answer:

If we asssume 1st equation as: 32x - 4y = 21

then the answer is: 26x -  7y = 12

Step-by-step explanation:

1. We need to subtract equation 2 from 1. So, we basically we have to do:

(32x - 4y = 21) - (6x +3y = 9)

2. Now, after opening the bracket, the second equation becomes:

- 6x - 3y = -9    ----------------- (eq 3)

3. Finally subtract the equation 3 from eq 1:

 32x -  4y = 21

- 6x   ± 3y = ±9

--------------------

 26x -  7y = 12

---------------------
