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

Answer:

x=-3

y=6

Step-by-step 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

\frac{8x}{8} =\frac{-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 }

<em>hope this helps....</em>
