Question

How can I solve this math problem?

Answer 1

`(-1,-3)`

Explanation:

`x+6y=-19`

Subtract 6y from both sides

`x=-19-6y`

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

`3x-7y=18`

Divide everything by 3

`x -(7)/(3)y =6`

`x=6+(7)/(3)y`

Substitute the x value to the other equation

`6+(7)/(3)y+6y=-19`

Subtract both sides by 6

`(7)/(3)y+6y=-25`

`6(7)/(3)y=-25`

`(25)/(3)y=-25`

`y=-3`

`x+6(-3)=-19`

`x+-18=-19`

`x=-1`
