Given : 7y=8x-14 and y =6

We plug in 6 for y in the given equation

Statement                      Reason

7y=8x-14, y=6                  Given

7(6)= 8x-14                      Substitution

56 = 8x                          Add 14 on both sides

7 = x                               divide by 8 on both sides

Hence proved x=7
