Solving the Equation: 0.3(6-2y) = 4.5 - 0.7(y+9)
This article will guide you through the steps of solving the equation 0.3(6-2y) = 4.5 - 0.7(y+9).
Step 1: Distribute
First, we need to distribute the constants on both sides of the equation:
- 0.3(6-2y) = 4.5 - 0.7(y+9)
- 1.8 - 0.6y = 4.5 - 0.7y - 6.3
Step 2: Combine Like Terms
Next, we'll combine the constant terms and the terms with 'y' on each side of the equation:
- 1.8 - 0.6y = 4.5 - 0.7y - 6.3
- 1.8 - 0.6y = -1.8 - 0.7y
Step 3: Isolate the 'y' term
We need to get all the 'y' terms on one side of the equation and the constant terms on the other side. Let's add 0.7y to both sides:
- 1.8 - 0.6y + 0.7y = -1.8 - 0.7y + 0.7y
- 1.8 + 0.1y = -1.8
Step 4: Isolate 'y'
Now, subtract 1.8 from both sides:
- 1.8 + 0.1y - 1.8 = -1.8 - 1.8
- 0.1y = -3.6
Step 5: Solve for 'y'
Finally, divide both sides by 0.1 to isolate 'y':
- 0.1y / 0.1 = -3.6 / 0.1
- y = -36
Solution
Therefore, the solution to the equation 0.3(6-2y) = 4.5 - 0.7(y+9) is y = -36.
