Simplifying 2(r2 + 1) = 5x Reorder the terms: 2(1 + r2) = 5x (1 * 2 + r2 * 2) = 5x (2 + 2r2) = 5x Solving 2 + 2r2 = 5x Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 2r2 = -2 + 5x Combine like terms: 2 + -2 = 0 0 + 2r2 = -2 + 5x 2r2 = -2 + 5x Divide each side by '2'. r2 = -1 + 2.5x Simplifying r2 = -1 + 2.5x Reorder the terms: 1 + r2 + -2.5x = -1 + 2.5x + 1 + -2.5x Reorder the terms: 1 + r2 + -2.5x = -1 + 1 + 2.5x + -2.5x Combine like terms: -1 + 1 = 0 1 + r2 + -2.5x = 0 + 2.5x + -2.5x 1 + r2 + -2.5x = 2.5x + -2.5x Combine like terms: 2.5x + -2.5x = 0.0 1 + r2 + -2.5x = 0.0 The solution to this equation could not be determined.
