Question

30 + 30x = 25 + 55x
solve for x
can someone help?

Answer 1

first combine like terms, so when you switch from one side to another just change the sign as follows:

30 -25 = 55x - 30x can you take it from here ?

Answer 2

I did that and I got 1/5 but it didn't fit the scenario

Answer 3

I know why, you did the equation wrong, it should be

30x +30 = 25x + 55 try it now

Answer 4

so now you have

30x -25x = 55 - 30 what do you get ?

Answer 5

Answer 6

im working on it right now

Answer 7

okay so from there this is what i got:

30x + 30 = 25x + 55
30x - 25x = 55 - 30
5x = 25
-- --
5 5
x = 5

==============
Then put it back into the equation

30(5) + 30 = 25(5) + 55
150 + 30 = 125 + 55
180 = 180

Answer 8

your only mistake was when you set up the equations the first time.
25 + 55x would mean 55 per yard plus 25
you really want 25 x +55 (meaning 25 per yard) plus 55

Answer 9

yeah @phi i got it mixed up when i was thinking of it, im pretty sure I got it now! thank you guys!!!!
