Question

Can you explain what went wrong and the actual answers these 3

Answer 1

For the first one, they got rid of the 6x when they shouldn’t have, and the correct answer is x = 21.5


For the second one, 47 would be subtracted by 180, not 90, and the correct answer is 133


For the third one, 5x - 10 doesn’t equal 115, 5x - 10 equals 180 - 115, and the correct answer is x = 17

Answer 2

Answer:

k i am going to tell you what's wrong with all of them, then i will give you the right answer

For the first one they did not combine the variable correctly

the second one needs to use 180, not 90

the third one is not set up like the first one and is supposed to. (115+5x+10=180)

1) 21.5

2) 133

3) 11

Hope this helps!! Have a good day and remember to be tiger fierce!! :)
