Solve inequalities the way you would solve an equation except for this rule-
If you multiply or divide a negative, the sign must be switched.
Do the inverse of everything like in an equation-
4x-1> -9
+1 +1 (Add 1)
4x>-8
/4 /4 (Divide 4)
You are not dividing a negative number from another number. So keep the sign.
x>-2
Your answer is C.
You will need to give at least 2 values to plug in to solve the equation.
However, to solve for a single variable, you need to isolate it.
See picture taken as in how to solve for one variable.
