What is the solution to the equation 7 −3x ≈ 9?

Question

anonymous · Answer

x = 0.376
 x = 0.295
 x = −0.295
 x = −0.376

nikato · Answer

your goal is to isolate x on one side.

1. subtract 7 on both sides.
2. divide both sides by -3.

anonymous · Answer

so the different equals sign doesnt really matter @nikato

anonymous · Answer

7-3x=9
-3x=9
       -7
-3x=2/-3
x=?
