How do I solve this?
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

To complete the two-column proof, we need to use properties of equality to manipulate the given equation and find the value of y.
Given: 11x – 6y = –1; x = 8
First, we substitute the value of x (which is 8) into the equation:
11(8) – 6y = –1
Now we simplify the equation:
88 – 6y = –1
Next, we want to isolate the variable y, so we subtract 88 from both sides of the equation:
–6y = –1 - 88
–6y = –89
To find the value of y, we divide both sides of the equation by -6:
y = (-89) / (-6)
Simplifying the division:
y = 89/6
Therefore, we have proved that 89/6 = y.
The correct answer for the two-column proof is:
a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Reflexive Property of Equality
