Solution for 2[d-(4d+18)+16]=2(d+2) equation:


Simplifying
2[d + -1(4d + 18) + 16] = 2(d + 2)

Reorder the terms:
2[d + -1(18 + 4d) + 16] = 2(d + 2)
2[d + (18 * -1 + 4d * -1) + 16] = 2(d + 2)
2[d + (-18 + -4d) + 16] = 2(d + 2)

Reorder the terms:
2[-18 + 16 + d + -4d] = 2(d + 2)

Combine like terms: -18 + 16 = -2
2[-2 + d + -4d] = 2(d + 2)

Combine like terms: d + -4d = -3d
2[-2 + -3d] = 2(d + 2)
[-2 * 2 + -3d * 2] = 2(d + 2)
[-4 + -6d] = 2(d + 2)
