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.
\[ \frac{ 48x }{ 48 } =\frac{ 69 }{ 48 }\]
\[ x =\frac{ 23 }{ 16 }\]
