x = -4, x = 5

Step-by-step explanation:

You can use the substitution method for this problem.

y = + 2x, but y also = 3x +20.

Because of this, you can determine that +2x = 3x + 20 because they are both equal to the same thing, y.

Solve the quadratic equation you got from substitution:

+ 2x = 3x + 20

-x = 20

-x -20 = 0

You can factor this equation:

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

x = -4, x = 5

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

its line 2 i just added the rest or else it wouldn't let me answer
