(−6−2)d
Subtract the numbers
−8d
−14−8d
−14−8d=0
Move the constant to the right-hand side and change its sign
−8d=0+14
Removing 0 doesn't change the value,so remove it from the expression
−8d=14
Change the signs on both sides of the equation
8d=−14
Divide both sides
88d=8−14
Divide the numbers
d=8−14
