Another question...

OpenStudy (pflori1234_pop):

9(2x -5)=-6(5x-4)

OpenStudy (pflori1234_pop):

the answer is x= 23/16.... i need help with the steps tho @AloneS

alones (alones):

Lol i got the same answer okay let me try to explain it ;)

OpenStudy (pflori1234_pop):

ok thanks...

OpenStudy (pflori1234_pop):

i keep getting 21/48... idk what I'm doing wrong

alones (alones):

At first you have to simplify both sides of the equation. 9(2x−5)=−6(5x−4) (9)(2x)+(9)(−5)=(−6)(5x)+(−6)(−4) 18x + − 45 = −30x + 24 18x − 45 = − 30x + 24

OpenStudy (pflori1234_pop):

oh wait thats what I'm doing wrong... how did you get a positive 24

alones (alones):

than add 30x to both sides 18x−45+30x=−30x+24+30x 48x−45=24 Okay again lol add 45 to both sides 48x−45+45=24+45 48x=69 But that's not all

alones (alones):

Finally at last divide both sides by 48. \[ \frac{ 48x }{ 48 } =\frac{ 69 }{ 48 }\] \[ x =\frac{ 23 }{ 16 }\]

OpenStudy (pflori1234_pop):

omg thank you so much.... that makes so much more sense now!

alones (alones):

Oh lol made my brain move too, My pleasure ;)
