Question

x+3x+6x-20=180 x=10 how do I get 10 for x?

Answer 1

collect like terms on the left to get
\[ 10x-20=180\] then add 20 to both sides to get
\[10x=200\] so
\[x=20\] not 10

Answer 2

in my math lab for class it gives me the answer x=10 but I can figure out how they came up with 10?? it takes me to the next step being 10x-20=180

Answer 3

oh i see, you are not asking for x, just what is
\[x+3x+6x\] which is
\[10x\] for the same reason that a bottle of beer plus 3 bottles of beer plus 6 bottles of beer is ten bottles of beer

Answer 4

OHH I got it now because x is alone in the equation it equals one so x+3+6=10 right?

Answer 5

thanks

Answer 6

Think of the "alone" x as 1x.

Then, x+3x+6x-20=180
1x + 3x + 6x - 20 = 180

10x = 200
