Parabolas: find x-val where y=-2x+20 intersects y=2x^2+3x-22

[Rachellowes]

Please help me with the following problem...

Find the values of x where the line y = -2x + 20 intersects the parabola y = 2x squared + 3x - 22

thank you.

Solve simultaneously. Since y = this and y = that, then, this = that. (You'll end up with a quadratic equation to solve.)
Give it a go.

Find the values of x where the line y = -2x + 20 intersects the parabola y = 2x squared + 3x - 22

We type exponents using the caret symbol, like this:

y = 2x^2 + 3x - 22

Please show us your work so far. We need to see what kind of mistakes you're making. Thanks.
