Question

mathmale · Answer

What have you thought of doing, so far?
Two possible ways of doing this problem:

Solve x+y=1 for either x or y.

If you solve for x, then substitute the resulting expression in y into the quadratic equation.

If you solve for y , then subst. the res. expr. in x into the quad. eq'n.

campbell_st · Answer

rewrite the linear equation as 

y = 1 - x

and equate them 

$$1 - x = x^2 +4x + 3$$
