Describe and correct
the error in solving the equation (20 points).

-1.5+k = 8.2
k = 9.7 (as you add 1.5 to both sides)

*you do not subtract 1.5 from both sides, you add it to both sides.
as if you rearrange the left side of the equation, it’ll be k-1.5. therefore, you have to add 1.5 to make it k. since you have to do the same to both sides, you have to add 1.5 to both sides!
