1. solve for y: 2y-3<9+y
2. solve for x: 7-2x>3y
Treat inequality just like an equation, except when multiplying/dividing by a negative number, which reverses the direction of the carat (> to <).
1. Subtract y and add 3 to both sides of the inequality.
2. Subtract 7 and then divide by -2 on both sides.
