Question 106053
From the problem description, you can write: (n = the missing number)
2(3n-12) = -42 "If 12 is subtracted from 3 times a number (3n-12) and the difference is multiplied by 2, (2(3n-12)) the result is (=) -42"
Simplify and solve for n.
2(3n-12) = -42 Apply the distributive property to the left side.
6n-24 = -42 Add 24 to both sides.
6n = -18 Finally, divide both sides by 6.
n = -3
