The solution of 2x2 + x = 3 is shown below. 2x2 + x - 3= 0
(2x + 3)(x - 1) = 0
x = -1.5 or x = 1
Based on this work, the solution of the system of
equations is
DONE
{(-1.5, -6.5), (1, 7)}
{(-1.5, 9.5), (1, 7)}
{(-1.5, 9.5), (1,9)}

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

How many solutions does the nonlinear system of equations graphed below have?
