@jim_thompson5910

jimthompson5910 (jim_thompson5910):

9+3x+1-2x 9+1+3x-2x (9+1)+(3x-2x) (10)+(1x) 10+1x 10+x

jimthompson5910 (jim_thompson5910):

if you were doing (9+3x)-(1-2x) then it'd be a different story

OpenStudy (anonymous):

ohhh ok so it's 10 ok

OpenStudy (anonymous):

10x+1

jimthompson5910 (jim_thompson5910):

no not 10x+1

jimthompson5910 (jim_thompson5910):

look back at my steps

OpenStudy (anonymous):

why does the 1 just disappear?

jimthompson5910 (jim_thompson5910):

1x is the same as just x

jimthompson5910 (jim_thompson5910):

since 1*x = x

jimthompson5910 (jim_thompson5910):

1 * (any number) = same number

OpenStudy (anonymous):
