21*x= 7

Trying to find x

21*x= 21x

21x= 7

divide by 21 for both sides

21/21x= 7/21

cross out 21 and 21, divide by 21 . Then 1*1*x= x

x= 1/3

Answer : 21*1/3= 7

I would start with the standard form equation of the parallel line.
.. 5x -2y = 5(-2) -2(3) = -16
Then solve for y.
.. 2y = 5x +16 . . . add 2y+16; then divide by 2 for the next equation
.. y = (5/2)x +8 . . . . . . . corresponds to selection (B)
