Question

0.3x-(0.8-0.2x)=0.2-0.5x​

Answer 1

Step-by-step explanation:

Simplifying 0.3x + -1(0.8 + -0.2x) = 0.2 + -0.5x 0.3x + (0.8 * -1 + -0.2x * -1) = 0.2 + -0.5x 0.3x + (-0.8 + 0.2x) = 0.2 + -0.5x Reorder the terms: -0.8 + 0.3x + 0.2x = 0.2 + -0.5x Combine like terms: 0.3x + 0.2x = 0.5x -0.8 + 0.5x = 0.2 + -0.5x Solving -0.8 + 0.5x = 0.2 + -0.5x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5x' to each side of the equation. -0.8 + 0.5x + 0.5x = 0.2 + -0.5x + 0.5x Combine like terms: 0.5x + 0.5x = 1x -0.8 + 1x = 0.2 + -0.5x + 0.5x Combine like terms: -0.5x + 0.5x = 0.0 -0.8 + 1x = 0.2 + 0.0 -0.8 + 1x = 0.2 Add '0.8' to each side of the equation. -0.8 + 0.8 + 1x = 0.2 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + 1x = 0.2 + 0.8 1x = 0.2 + 0.8 Combine like terms: 0.2 + 0.8 = 1 1x = 1 Divide each side by '1'. x = 1 Simplifying x = 1
