Fill in the reasons in the proof:

1) Given: 0 = -16x + 20, solve for x:
StatementReason
0 = -16x + 20
-20 = -16x
5/4 = x
x = 5/4






2) Given: -9 = -19x -8, solve for x:
StatementReason
-9 = -19x -8
-1 = -19x
1/19 = x
x = 1/19
3) Given: 19 = -17x, solve for x:
StatementReason
19 = -17x
-19/17 = x
x = -19/17






4) Given: -17 = -11x + 7, solve for x:
StatementReason
-17 = -11x + 7
-24 = -11x
24/11 = x
x = 24/11
