solve the compound inequality write the solution in interval notation
2u+4>-6 and 3u-6> -3 =
Solve each one individually:
u > -1
3u > 3
Draw a number line and put an open circle or a ( at -1 and 1
from -1 you will draw an arrow to the right on the number line
from 1 you will draw an arrow to the right on the number line.
AND means your answer is where the arrows overlap.
The overlap should start at 1 and to to infinity.
The final answer is x>1
