Wane was asked to solve the inequality 
He decides that he needs to multiply both sides by 3.
We need to tell if the step is correct?
So, solving the inequality

We need to multiply both sides by 3, to get value of x i.e.

So, Wanes step is correct.
The correct option is Option A: Yes, that is the correct step
u - v = <6 - 1, -9 - (-4)> = <5, -5> . . . . . . . matches selection A)
_____
The sum or difference of vectors is simply the sum or difference of corresponding coordinates.
To solve for X: First you multiply x and 6 then subtract 21 on both sides and then divide by 6
531 = ( X × 6) + 21
531 = 6X + 21
510 = 6X
85 = X
