Answer» Step-by-step EXPLANATION: Simplifying 6x + -10 = 2x + -30 Reorder the terms: -10 + 6x = 2x + -30 Reorder the terms: -10 + 6x = -30 + 2x Solving -10 + 6x = -30 + 2x Solving for variable 'X'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -10 + 6x + -2x = -30 + 2x + -2x Combine LIKE terms: 6x + -2x = 4x -10 + 4x = -30 + 2x + -2x Combine like terms: 2x + -2x = 0 -10 + 4x = -30 + 0 -10 + 4x = -30 Add '10' to each side of the equation. -10 + 10 + 4x = -30 + 10 Combine like terms: -10 + 10 = 0 0 + 4x = -30 + 10 4x = -30 + 10 Combine like terms: -30 + 10 = -20 4x = -20 Divide each side by '4'. x = -5 Simplifying x = -5 |
