Step-by-step explanation:
Simplifying
d + - 5 = 7
Reorder the terms:
-5 + d = 7
Solving
-5 + d = 7
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + d = 7 + 5
Combine like terms: - 5 + 5 = 0
0 + d = 7 + 5
d = 7 + 5
Combine like terms: 7 + 5 = 12
d = 12
Simplifying
d = 12
