oh okay, so yeah you apply the cross product as you had written up above, to get, 2x = 84 (do you understand this part?)

So you do know how to cross multiply ?

okay now, to find the value of x, we need to isolate it, do you have any ideas on how we can do this?

just checking......but do you understand how you got 2x = 84 ?

okay so we have 2x = 84, so to avoid changing the equation, whatever we do to one side, we must also do to the other, so in this case, to get rid of the coefficient of x, we can divide both sides by 2, so we get; 2x/2 = 84/2 which we can now simplify to x = 42. Do you understand?

so the anwser is 42?
FireKat97
  • FireKat97
yup because we divided 84 by 2 and that simplifies down to 42
