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.
