Answer:

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
