could someone help me with math?

Question

Solve the following inequality for y

7x-2y≥14

Answer 1

Solve for y means to rearrange the inequality so that y is alone (which side does not matter).

 

7x - 2y ≥ 14

- 2y ≥ -7x + 14         subtract 7x form both sides

y ≤ 7x/2 - 7               divide both sides by -2

 

When multiplying or dividing both sides of an inequality, the order (direction) of the inequality sign (<, >, ≤, ≥) reverses.
