Here are a few problems I need solving Make sure to show a check for the solution and write the solution in set notation like {xx>5}:
Solve for y
7y14>42
Solve for x
2(4x+5) < 2x20

I do not know set notation. When multiplying/dividing both sides of an inequality by a negative, reverse the carat.
7y > 56
y < 8
8x + 10 < 2x  20
10x < 30
x > 3

I goofed with a sign. It should be:
8x  10 < 2x  20
10x < 10
x > 1
