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