Question

Plz help me guys... :(

Answer 1

(-1,8)

Explanation:

The easiest method would be using substitution:

`\left \{ {{-10x+3y=34} \atop {y = -8x}} \right.`

Substitute the second equation into the first one:

`-10x + 3(-8x)=34`

`-10x+-24x = 34`

`-34x = 34`

`x = -1`

Use the x-value to get the y-value:

`y = -8*-1`

`y = 8`

Final answer:

(-1,8)
