Problem
34x+54y=30
Solution
Now, do not let the fractions freak you out! We’re about to make them disappear. (The best kind of mathematical magic act, right?)
Both fractions have a denominator of 4
which means that we can multiply ALL terms by the denominator 4
. You must multiply to all three terms, including the C
term on the right side! Based on the rules of algebra, we are allowed to do this multiplication because we are multiplying it to every term.
4(34x+54y)=4(30)
By multiplying by 4
, it eliminates the denominators of our fractions and just leaves us with the numerators. Make sure to multiply 4(30)
.
3x+
y=
We now have an equation written properly in Standard Form. All coefficients are integers.
