Simplifying (R + -3)(r + -5) = 0 Reorder the terms: (-3 + R)(r + -5) = 0 Reorder the terms: (-3 + R)(-5 + r) = 0 Multiply (-3 + R) * (-5 + r) (-3(-5 + r) + R(-5 + r)) = 0 ((-5 * -3 + r * -3) + R(-5 + r)) = 0 ((15 + -3r) + R(-5 + r)) = 0 (15 + -3r + (-5 * R + r * R)) = 0 (15 + -3r + (-5R + rR)) = 0 Reorder the terms: (15 + -5R + -3r + rR) = 0 (15 + -5R + -3r + rR) = 0 Solving 15 + -5R + -3r + rR = 0 Solving for variable 'R'. Move all terms containing R to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -5R + -3r + -15 + rR = 0 + -15 Reorder the terms: 15 + -15 + -5R + -3r + rR = 0 + -15 Combine like terms: 15 + -15 = 0 0 + -5R + -3r + rR = 0 + -15 -5R + -3r + rR = 0 + -15 Combine like terms: 0 + -15 = -15 -5R + -3r + rR = -15 Add '3r' to each side of the equation. -5R + -3r + 3r + rR = -15 + 3r Combine like terms: -3r + 3r = 0 -5R + 0 + rR = -15 + 3r -5R + rR = -15 + 3r Reorder the terms: 15 + -5R + -3r + rR = -15 + 3r + 15 + -3r Reorder the terms: 15 + -5R + -3r + rR = -15 + 15 + 3r + -3r Combine like terms: -15 + 15 = 0 15 + -5R + -3r + rR = 0 + 3r + -3r 15 + -5R + -3r + rR = 3r + -3r Combine like terms: 3r + -3r = 0 15 + -5R + -3r + rR = 0 The solution to this equation could not be determined.
