8d + 1 = 5d + 10 can someone please explain how to solve this?
spayn [35]
<span>
Add '-1' to each side of the equation. 1 + -1 + 3d = 10 + -1 Combine like terms: 1 + -1 = 0 0 + 3d = 10 + -1 3d = 10 + -1                                                                      

Combine like terms: 10 + -1 = 9 3d = 9

Divide each side by '3'. d = 3 Simplifying
