Answer:
x < 3 and x > 2
Step-by-step explanation:
I don't know if you want both questions answered, so have them anyways:
1) 3x+1<10
Subtract 1 on both sides, resulting 3x<9
Then divide by 3 to both sides, resulting x < 3
(The graph will have an open circle on 3 then an arrow pointing to the left.)
3) -2x+22<18
Subtract 22 on both sides, resulting -2x < -4
Then divide by -2 to both sides. Since you are dividing by a negative number, the sign changes: x > 2
(The graph will have an open circle on 2 with an arrow pointing to the right.)
