Question

complete the two column proof.

Given: 11x -6y = -1; x = 8
Prove 89/6 = y

11x - 6y = -1; x =8
88 - 6y= -1
-6y = -89
y = 89/6

89/6 =y

Answer 1

Statement | Reason
1. 11x - 6y = -1; x = 8 | Given
2. 11(8) - 6y = -1 | Substitution property of equality
3. 88 - 6y = -1 | Simplification
4. -6y = -1 - 88 | Subtraction property of equality
5. -6y = -89 | Simplification
6. y = (-89)/(-6) | Division property of equality
7. y = 89/6 | Simplification
