Isolate d:d−12=1To solve for d, we need to isolate d on one side of the equation.We can do this by adding 12 to both sides of the equation to cancel out the −12 on the left side.d−12+12=1+12
Add 12:d=13After adding 12 to both sides, we find that d equals 13.This is the value of d that satisfies the equation.
