Multiply every term by 12.
Then solve the equation you get.
I didnt know how to name this topic, but hopefully someone can help
heres the equation:
(one-fourth y minus two thirds y equals 5)
1/4y - 2/3y = 5
I have the answer, which is -12. But can someone explain to me HOW to get the answer without plugging -12 in? When I start moving numbers to the other side I end up getting a number thats waay off by the end of it.
Thank you!
Two-thirds of some number subtracted from a quarter of the same number equals 5.
A quarter is just a value where the denominator is 4 times the numerator.
Also
We can add and subtract fractions with the same denominator...
Therefore...
Since LHS=RHS, then 12(LHS)=12(RHS)
so a shortcut is to multiply both sides by 12 to avoid having to combine the fractions.
