Answer:


  • \boxed{\sf{y=-5 \quad x=-18}}

Explanation:

The terms x and y must be substituted to isolate one side of the equation.

y=5/6x+10 and -x+6y=-12

First, you have to substitute by the y=5/6x+10.


\sf{-x+6\left((5)/(6)x+10\right)=-12}

Solve.


\sf{4x+60=-12}

Subtract by 60 from both sides.

4x+60-60=-12-60

Solve.

4x=-72

Divide by 4 from both sides.

4x/4=-72/4

Solve.

Divide the numbers from left to right.

-72/4=-18

x=-18

Substitute: x=-18


\sf{y=(5)/(6)\left(-18\right)+10}

Solve.

y=5/6(-18)+10=-5

y=-5

  • Therefore, the solution is y=-5 and x=-18, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.
