Calculate
−3(2k−4)
Apply the distributive property
−3×2k−(−3×4)
Multiply the numbers
−6k−(−3×4)
Multiply the numbers
−6k−(−12)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−6k+12
24−6k+12
Add the numbers
36−6k
36−6k=0
Move the constant to the right-hand side and change its sign
−6k=0−36
Removing 0 doesn't change the value,so remove it from the expression
−6k=−36
Change the signs on both sides of the equation
6k=36
Divide both sides
66k=636
Divide the numbers
k=636
