first, distribute
20x + 12 = 14x + 30

next, move the variable over to one side by using opposite functions (subtract 14x from each side)
6x + 12 = 30

subtract 12
6x = 18

divide by 6
x = 3

the answer is C. x = 3

Answer:

C. x = 3

Step-by-step explanation:

First you should bring expand the bracket to make things easier:

4 ( 5x + 3 ) = 14x + 30

20x + 12 = 14x + 30

Next, you should bring all x terms to one side and whole numbers to the other:

20x - 14x = 30 - 12

Then you bring the terms together:

6x = 18

Now you isolate x by dividing each side by 3:

x = 3

The answer is x = 3.
