How Do You Solve a Two-Step Equation by Distributing a Fraction First?
Solve the following problem: (2/3)(x-2)=4
Summary
- First we distribute the 2/3
- Use the addition property of equality to move the 4/3
- LCD stands for least common denominator
- Multiply 4/1 by 3 on the top and bottom to get 12/3
- Multiplying 2/3 by its reciprocal, 3/2, will cancel it out on the left hand side

Notes
-
- To distribute, you'll have to multiply the 2/3 by everything inside the parentheses
- So (2/3)•x is (2/3)x
- And (2/3)•(-2) is -4/3
- You'll end up with (2/3)x-4/3 on the left hand side
-
- The addition property of equality says that we can add 4/3 to both sides without changing the equality
-
- 4 can be represented as the fraction 4/1
- The least common denominator is 3, so we have to change 4/1 into a fraction with a 3 in the denominator so we can add it to 4/3
- Multiply 4/1 by 3 on both the top and bottom to get 12/3
- 12/3 plus 4/3 is 16/3
-
- A reciprocal of a fraction is the flipped version of that fraction
- So, the reciprocal of (2/3) is (3/2)
- If we multiply 2/3 by its reciprocal, it cancels out and leaves us with just x on the left hand side
