Question

What is the solution to this system of linear equations? 7x – 2y = –6 8x y = 3 (–6, 3) (0, 3) (1, –5) (15, –1)

Answer 1

Answer: B

Explanation:

Answer 2

`(0,3)`

Explanation:

we have

`7x-2y=-6` ----> equation A

`8x+y=3` ----> equation B

Multiply the equation B by 2 both sides

`2(8x+y)=2*3`

`16x+2y=6` ------> equation C

Adds equation A and equation C

`7x-2y=-6\\16x+2y=6\\--------\\7x+16x=-6+6\\23x=0\\x=0`

Find the value of y

`7(0)-2y=-6`

`-2y=-6`

`y=3`

the solution is the point
`(0,3)`
