Simplifying 3(d + -4) + d(d + 4) = d(d + 1) Reorder the terms: 3(-4 + d) + d(d + 4) = d(d + 1) (-4 * 3 + d * 3) + d(d + 4) = d(d + 1) (-12 + 3d) + d(d + 4) = d(d + 1) Reorder the terms: -12 + 3d + d(4 + d) = d(d + 1) -12 + 3d + (4 * d + d * d) = d(d + 1) -12 + 3d + (4d + d2) = d(d + 1) Combine like terms: 3d + 4d = 7d -12 + 7d + d2 = d(d + 1) Reorder the terms: -12 + 7d + d2 = d(1 + d) -12 + 7d + d2 = (1 * d + d * d) -12 + 7d + d2 = (1d + d2) Add '-1d2' to each side of the equation. -12 + 7d + d2 + -1d2 = 1d + d2 + -1d2 Combine like terms: d2 + -1d2 = 0 -12 + 7d + 0 = 1d + d2 + -1d2 -12 + 7d = 1d + d2 + -1d2 Combine like terms: d2 + -1d2 = 0 -12 + 7d = 1d + 0 -12 + 7d = 1d Solving -12 + 7d = 1d Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add '-1d' to each side of the equation. -12 + 7d + -1d = 1d + -1d Combine like terms: 7d + -1d = 6d -12 + 6d = 1d + -1d Combine like terms: 1d + -1d = 0 -12 + 6d = 0 Add '12' to each side of the equation. -12 + 12 + 6d = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 6d = 0 + 12 6d = 0 + 12 Combine like terms: 0 + 12 = 12 6d = 12 Divide each side by '6'. d = 2 Simplifying d = 2
