111d4
111d4−100=0
Move the constant to the right-hand side and change its sign
111d4=0+100
Removing 0 doesn't change the value,so remove it from the expression
111d4=100
Divide both sides
111111d4=111100
Divide the numbers
d4=111100
Take the root of both sides of the equation and remember to use both positive and negative roots
