(−14−1)d
Subtract the numbers
−15d
−15d−9
−15d−9=0
Move the constant to the right-hand side and change its sign
−15d=0+9
Removing 0 doesn't change the value,so remove it from the expression
−15d=9
Change the signs on both sides of the equation
15d=−9
Divide both sides
1515d=15−9
Divide the numbers
d=15−9
