Final Result : 2 • (5c - 2d)

Simplifying 3c + -9d + 7c + 5d = 0 Reorder the terms: 3c + 7c + -9d + 5d = 0 Combine like terms: 3c + 7c = 10c 10c + -9d + 5d = 0 Combine like terms: -9d + 5d = -4d 10c + -4d = 0 Solving 10c + -4d = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '4d' to each side of the equation. 10c + -4d + 4d = 0 + 4d Combine like terms: -4d + 4d = 0 10c + 0 = 0 + 4d 10c = 0 + 4d Remove the zero: 10c = 4d Divide each side by '10'. c = 0.4d Simplifying c = 0.4d
