Equation with Variables
by: Karin

This equation looks intimidating because of the fractions. Therefore, our first step will be to get rid of the fractions.

Step 1: Get rid of the fractions by multiplying all terms by the least common multiple, 6.

6[2/3] = 6[4J/6)
4 = 4J

Step 2: Divide both sides by 4.

4/4 = 4J/4
1 = J

Step 3: Check your answer

2/3 = 4(1)/6
2/3 = 2/3

The answer, J = 1 is correct.
