Answer:

142 is x

Step-by-step explanation:

by creatin the inequality 14x+24=180 we know that and straight line is 180 degrees and 14x is 9x+5x and 24 is 20 +4. we can now solve by  doing the following below:

14x+24=180

      -24  | -24

180-24=156

bring down the 14x now we have

14x=156

-14 | -14

156-14 is 142 so x=142
