Subject: Liner Equasions (Algebra 1)
My dad and I have been trying to figure, how to solve for x on any of these problems my teacher gives us. The problem is:
2h/3 + 1/2 = 5h/6 - 3/4
The first thing to realize is that an equation remains true if you multiply both sides of an equation by any number that you wish. If you look at the denominators of the fractions you will see 3, 2, 6, 4. Think of what a common denominator for these numbers could be. The simplest one is 12 since all the numbers are divisors of 12. So, instead of changing all the denominators to 12 you just need to multiply every term of both sides of the equation by 12. (Since the two sides of the equation are equal they will still be equal after you have 12 times as much on each side.)
