Question

6. What are the solutions of:
a. X +_ 9 < 12
b. 7 ≤ x + 3
c. T + 3 > -1

Answer 1

well you just need to take constants to RHS and keep the variable in LHS

Answer 2

infact there is no strict rule in taking to LHS or RHS what you need to keep in mind is that the variable alone should be present in one side while the constant is present in other side.
