Answer:
3:7
Step-by-step explanation:
b is the same in both so it would just be 3:6:7 without b which is 3:7
Compare both sides,
x² - x - 1 = 2 - 3x
x² + 2x - 3 = 0
x² -x + 3x - 3 = 0
x(x - 1) 3(x - 1) = 0
(x - 1)(x+3) = 0
x = 1 or - 3
In short, Your Answers would be 1 & -3
Hope this helps!

3x - 1 = 20 - 7 - 7
3x -1 = 20
3x - 1 + 1 = 20 + 1
3x = 21
3x/3 = 21/3
x = 7
