Answer
A) $y\lt-10$
Work Step by Step
To solve an inequality for a given variable, isolate the variable on one side of the inequality.
$y-7\gt3+2y$
Subtract y from each side.
$y-7-y\gt3+2y-y$
Simplify.
$-7\gt3+y$
Subtract 3 from each side.
$-7-3\gt3+y-3$
Simplify.
$-10\gt y$
Which can also be written as:
$y\lt-10$
