Question

In the solution of the equation 5 - 3x = 2x + 9, 3x is added to the equation first. Which of the following should be done next?

add -9
add -5
add -2x

Answer 1

they add 3x and this is what we get:

5 - 3x (+3x) = 2x + 9 (+3x)

Answer 2

we can combine the x terms:

-3x (+3x) = 0
2x (+3x) = 5x

Answer 3

so if the only possible answers are

add -9
add -5
add -2x
it would be add -5

Answer 4

if you add 3x to both sides you get

5 = 5x + 9

Answer 5

okay yes i know the answer know thank you
