Question

Solve using the elimination method. 2x + 7y = 36
6x - 7y = - 60 ​

Answer 1

`x=-3`

`y=6`

Explanation:

Elimination method:

`2x+7y=36`

`6x-7y=-60`

Add these equation to eliminate y:

`8x=-24`

Then solve
`8x=-24` for x:

`8x=-24`

`(8x)/(8) =(-24)/(8)`

`x=-3`

Add the value of x to solve y:

`2x+7y=36`

Substitute
`-3` for x in
`2x+7y=36`

`(2)(-3)+7y=36`

`7y-6=36`

`7y=36+6`

`7y=42`

`y=42/7\\`

`y=6`

{
`x=-3` and
`y=6` }

hope this helps....

Answer 2

Point form: (-3,6)
Equation form: x=-3, y=6
