Answer:

x = -4 and x = 5

Step-by-step explanation:

Since $x^2 + 2x$ and $3x + 20$ both equal to y, we know that the expressions equal to each other. We can write a new equation base on that.

$x^2 + 2x = 3x + 20$

Now we solve the equation.

$x^2 + 2x = 3x + 20$

$x^2 - x = 20$

$x^2 - x - 20 = 0$

$(x + 4) (x - 5) = 0$

$x + 4 = 0 ; x -5 = 0$

$x = -4 ; x = 5$
