Solve the system below using the substitution method y=2x^2+7x-1 14+2y=24x Please show all you work.

1 answer

from your 2nd equation:
14+2y=24x
7 + y = 12x
y = 7-12x
Now you have 2 equations that say y = ... , so
2x^2 + 7x - 1 = 7-12x
2x^2 + 19x - 8 = 0

Too bad it doesn't factor, so use the formula to find the
two solutions.
