Solution for d+2+5(d-1)=d+2(3d-5) equation:


Simplifying
d + 2 + 5(d + -1) = d + 2(3d + -5)

Reorder the terms:
d + 2 + 5(-1 + d) = d + 2(3d + -5)
d + 2 + (-1 * 5 + d * 5) = d + 2(3d + -5)
d + 2 + (-5 + 5d) = d + 2(3d + -5)

Reorder the terms:
2 + -5 + d + 5d = d + 2(3d + -5)

Combine like terms: 2 + -5 = -3
-3 + d + 5d = d + 2(3d + -5)

Combine like terms: d + 5d = 6d
-3 + 6d = d + 2(3d + -5)

Reorder the terms:
-3 + 6d = d + 2(-5 + 3d)
-3 + 6d = d + (-5 * 2 + 3d * 2)
-3 + 6d = d + (-10 + 6d)

Reorder the terms:
-3 + 6d = -10 + d + 6d
