When the value of the independent variable x satisfies what conditions, the value of the function y = 5x + 17 satisfies the following conditions (please write in the image method) （1）y=0 （2）y=-7 （3）y=20 Note: it should be represented by image method

1. When y = 0, 5x + 17 = 0
x=-17/5
2. When y = - 7, 5x + 17 = - 7
x=-24/5
3. When y = 20, 5x + 17 = 20
x=3/5
