Answer: 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
