Solve the systems 3x2 2y 26 5x2 7y 3Solution3x2 2y 26

Solve the systems:

3x^2 + 2y = 26

5x^2 + 7y = 3

3x^2 + 2y = 26

5x^2 + 7y = 3

multiplying equation 1 by 5 and equation 2 by -3 and adding the two equation

15x^2 + 10y = 130

-15x^2 - 21y = -9

---------------------------

0 - 11y = 121

y = - 11

5x^2 + 7y = 3

5x^2 + 7 ( -11) = 3

5x^2 = 3 + 77

5x^2 = 80

x^2 = 16

x = + - 4

x = + - 4 , y = -11
