Question

16 < 3x + 1 < 4

Part 1: Solve the inequality above.
Part 2: Describe the graph of the solution.

Answer 1

ive done this kind of equation multiple times but i keep forgetting

Answer 2

you can do things to all three sides of the inequality

16 - 1 < 3x < 4 - 1
15 < 3x < 3
5 < x < 1

so x is between (not inclusive) 1 and 5

Answer 3

so -1 to all sides

Answer 4

then divide 3x to all sides

Answer 5

I think there is a problem with this, 16 is clearly not less than 4

Answer 6

not 3x, just 3

Answer 7

@Rowan's right. This doesn't work out. The values only work for x > 5 and x < 1

Answer 8

ok so then what would it be???

Answer 9

Your question is wrong. You cannot write it out like that

Answer 10

x > 5 and x < 1

Answer 11

ok and how would i graph it??
