HELP!!!!!! Find the solution to the system algebraically. Show all work for full credit. Leave your answers in fraction form. y=6x^2     7x+y=3

phi · Answer

the first equation says  y is equal to 6x^2

use that definition of y in the 2nd equation:

7x + y = 3

replace y with 6x^2
7x + 6x^2 = 3

put into standard form:
6x^2 + 7x -3 =0

can you solve this quadratic ?
