Simplifying 3(r + -1) = -2x(2 + r) Reorder the terms: 3(-1 + r) = -2x(2 + r) (-1 * 3 + r * 3) = -2x(2 + r) (-3 + 3r) = -2x(2 + r) -3 + 3r = (2 * -2x + r * -2x) Reorder the terms: -3 + 3r = (-2rx + -4x) -3 + 3r = (-2rx + -4x) Solving -3 + 3r = -2rx + -4x Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '2rx' to each side of the equation. -3 + 3r + 2rx = -2rx + 2rx + -4x Combine like terms: -2rx + 2rx = 0 -3 + 3r + 2rx = 0 + -4x -3 + 3r + 2rx = -4x Add '3' to each side of the equation. -3 + 3r + 3 + 2rx = 3 + -4x Reorder the terms: -3 + 3 + 3r + 2rx = 3 + -4x Combine like terms: -3 + 3 = 0 0 + 3r + 2rx = 3 + -4x 3r + 2rx = 3 + -4x Reorder the terms: -3 + 3r + 2rx + 4x = 3 + -4x + -3 + 4x Reorder the terms: -3 + 3r + 2rx + 4x = 3 + -3 + -4x + 4x Combine like terms: 3 + -3 = 0 -3 + 3r + 2rx + 4x = 0 + -4x + 4x -3 + 3r + 2rx + 4x = -4x + 4x Combine like terms: -4x + 4x = 0 -3 + 3r + 2rx + 4x = 0 The solution to this equation could not be determined.
