Question

One method for solving 3 ( x - 4 ) = 18 is 2/1÷3 then add four which method below would also result in the correct answer

Answer 1

One method for solving 3 ( x - 4 ) = 18 is to eliminate the parentheses first by distributing the 3 to both terms inside the parentheses:

3 ( x - 4 ) = 18
3x - 12 = 18

To solve for x, we can then add 12 to both sides to isolate the term with x:

3x - 12 + 12 = 18 + 12
3x = 30

Finally, we divide both sides by 3 to solve for x:

3x/3 = 30/3
x = 10

Another method that would result in the correct answer is:

3 ( x - 4 ) = 18

First, divide both sides by 3:

( x - 4 ) = 18/3
x - 4 = 6

Then, add 4 to both sides:

x - 4 + 4 = 6 + 4
x = 10

Both methods would yield the correct answer, which is x = 10.
