Question

How would I solve this for x? 

12/42 = x/14

anonymous · Answer

x=4, sorry

johnweldon1993 · Answer

You would multiply both sides of the equation by 14.....when you multiply say 11/14 by 14...the 14's cancel and all you have is 11

So for you

(12/42) * 14 = (x/14) * 14
you're left with

(12/42) *14 = x

Which yes...will come out to @kutabs answer of 4

Understandable??

Why am I multiplying both by 14?

johnweldon1993 · Answer

like I said....you want to isolate x.....and to do that....since x is being DIVIDED by 14 here....you do the INVERSE which is MULTIPLYING by 14....this cancels the dividing out and leaves you with JUST x on that right side

anonymous · Answer

because you need the value of x, and you've got the value of x/14 (equal to 12/42). Now, to get the value of x multiply both sides by 14 to that the RHS becomes (x/14)*14= x
