(-6+k)/2=-9
Step 1: Simplify both sides of the equation.
(−6+k)/2=−9, 1/2k-3=−9
Step 2: Add 3 to both sides.
1/2k=-6
Step 3: Multiply both sides by 2.
k=12
Hope that helps!

of 50 customers surveyed, 22 of them stated that they would buy a protection
plan.
On the next day, 700 customers came.
Let’s predict how many of them would probably buy the protection plan.
Ratio = 50 : 22 = 700 : x
=> 700 * 22 = 15 400
=> 15 400 / 50 = 308
Thus, if 700 customer came in the next day, around 308 of the customers will
buy life plan.</span>
