What can you do to isolate a variable in an inequality?
G
Inequalities can be solved in the same way as equations, by performing inverse operations on both sides until the variable is isolated. The only difference is that when we divide or multiply by a negative number, we must reverse the inequality sign.

Add terms
LHS+3x≥RHS+3x
Add terms
LHS+2≥RHS+2
.LHS /6.≥.RHS /6.
Calculate quotient
a/b=.a /3./.b /3.
This inequality tells us that all values greater than or equal to 12 will satisfy the inequality. Therefore, answer G is correct.
