Question

Subtract the equations.

7x +2y = 17
(3x +2y=3)
O A. 10x = 20
B. -4y= 14
OC. 4x=14
O D. 4y= 20​

Answer 1

The answer is C.

Step-by-step explanation:

As you subtract the equations, y variable will be eliminate :

`7x + 2y = 17 - - - (1)`

`3x + 2y = 3 - - - (2)`

`(1) - (2)`

`7x - 3x + 2y - 2y = 17 - 3`

`4x = 14`

Answer 2

Answer:C

Explanation:Eliminate the y variable so 2y-2y
