Question

Solve for Variable: 3x + 7 < 16 A. x > 3 B. x < 5 C. x > 6 D. x < 3

Answer 1

Answer:

D. x < 3

Step-by-step explanation:

3x + 7 < 16

To solve, we have to isolate x.

3x + 7 < 16

Subtract 7 from both sides :

3x < 9

Divide 3 from both sides :

x < 3

Now in some cases, you could say that the inequality sign would switch, but this is only when you divide by a negative sign, so keep that in mind.
