So the equation is 25 + d = 48
Simplifying
25 + d = 48
Solving
25 + d = 48
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-25' to each side of the equation.
25 + -25 + d = 48 + -25
Combine like terms: 25 + -25 = 0
0 + d = 48 + -25
d = 48 + -25
Combine like terms: 48 + -25 = 23
d = 23
Simplifying
d = 23
To make sure we are correct add 23 and 25
25 + 23 = 48
Answer: 23
