Solving the Equation: 0.2(x-3) = 0.4(7-x) - 4.6
This article will guide you through the steps of solving the equation 0.2(x-3) = 0.4(7-x) - 4.6.
Step 1: Distribute
Start by distributing the constants on both sides of the equation:
- 0.2(x-3) = 0.4(7-x) - 4.6
- 0.2x - 0.6 = 2.8 - 0.4x - 4.6
Step 2: Combine Like Terms
Next, combine the constant terms on the right side of the equation:
- 0.2x - 0.6 = -1.8 - 0.4x
Step 3: Isolate the Variable
To isolate the variable 'x', add 0.4x to both sides of the equation:
- 0.2x - 0.6 + 0.4x = -1.8 - 0.4x + 0.4x
- 0.6x - 0.6 = -1.8
Step 4: Continue Isolating the Variable
Add 0.6 to both sides of the equation:
- 0.6x - 0.6 + 0.6 = -1.8 + 0.6
- 0.6x = -1.2
Step 5: Solve for x
Finally, divide both sides by 0.6 to solve for 'x':
- 0.6x / 0.6 = -1.2 / 0.6
- x = -2
Solution
Therefore, the solution to the equation 0.2(x-3) = 0.4(7-x) - 4.6 is x = -2.
