Complete the two-column proof.

Given: 11x - 6y = - 1; x = 8

Prove: 89/6 = y

State what property each step is.

88 - 6y = - 1

-6y = - 89

y = 89/6

89/6 = y

88 - 6y = - 1 substitution property (as 8 is substituted to replace x)

-6y = - 89 subtraction property (88 is subtracted to the whole eqn)

y = 89/6 division property (-6 is the divisor)

89/6 = y transitive property (exchange of places results to the same value)
