Calculate
2(d−6)
Apply the distributive property
2d−2×6
Multiply the numbers
2d−12
2d−12−6
Subtract the numbers
2d−18
2d−18=0
Move the constant to the right-hand side and change its sign
2d=0+18
Removing 0 doesn't change the value,so remove it from the expression
2d=18
Divide both sides
22d=218
Divide the numbers
d=218
