what is the solution of 4x-30 greater than or equal to -3x +12

Question

greater than or equal to -----> >

Answer 1

Add 3x to both sides, and you have:

7x -30 >= 12.

Add 30 to both sides, and you get:

7x >= 42

Divide by 7.

x >= 6.

And if you're graphing that, it has a closed circle at 6 and points to the right!
