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: $y\lt-10$
