Answer
True
Work Step by Step
Since, we have $3y-1=11 $ and $3y-7=5$
Need to prove that the equations are equivalent.
Consider the first equation, $3y-1=11 $
or, $3y=11+1 \implies y=4$
Now, consider the second equation, $3y-7=5 $
or, $3y=5+7 \implies y=4$
From both the equations, we have $y=4$
Hence, the given statement is true.
