Solving the Equation: 0.8(5-x) - 1.2(x+4) = -2.8
This article will guide you through the steps of solving the given linear equation.
Step 1: Distribute
Begin by distributing the coefficients on both sides of the equation:
0.8(5-x) - 1.2(x+4) = -2.8
4 - 0.8x - 1.2x - 4.8 = -2.8
Step 2: Combine Like Terms
Combine the 'x' terms and the constant terms on the left side of the equation:
-2x - 0.8 = -2.8
Step 3: Isolate the Variable
Add 0.8 to both sides of the equation to isolate the 'x' term:
-2x = -2
Step 4: Solve for x
Divide both sides of the equation by -2 to solve for 'x':
x = 1
Conclusion
Therefore, the solution to the equation 0.8(5-x) - 1.2(x+4) = -2.8 is x = 1.
