Question

Solve:
11x-6y^2+7y= -14
x= -7y + 3

Answer 1

put the equation for x into the top equation and solve

Answer 2

\[11(-7y+3)-6y^2+7y=-14\]
\[-77y+33-6y^2+7y=-14\]
\[-70y-6y^2=-14-33\]
\[-70y-6y^2=-47\]
\[6y^2+70y-47=0\]
solve this quadratic equation

Answer 3

use the quadratic formula, it would be easier and faster
