a)⇒24/x=3/5. 8/3=85a)⇒24/x=3/5. 8/3=85 ⇒24x=2415⇒24x=2415 ⇒x=1/5⇒x=1/5 b)⇒2x+/72=97/4b)⇒2x+7/2=97/4 ⇒2x=97/4−72=83/4⇒2x=97/4-72=83/4 ⇒x=83/4:2=83/8 Trả lời
`a) => 24/x=3/5. 8/3=8/5` `=> 24/x=24/15` `=> x=15` `b) => 2x+ 7/2 = 97/4` `=> 2x=97/4 – 7/2=83/4` `=> x=83/4 : 2= 83/8` Trả lời
a)⇒24/x=3/5. 8/3=85a)⇒24/x=3/5. 8/3=85
⇒24x=2415⇒24x=2415
⇒x=1/5⇒x=1/5
b)⇒2x+/72=97/4b)⇒2x+7/2=97/4
⇒2x=97/4−72=83/4⇒2x=97/4-72=83/4
⇒x=83/4:2=83/8
`a) => 24/x=3/5. 8/3=8/5`
`=> 24/x=24/15`
`=> x=15`
`b) => 2x+ 7/2 = 97/4`
`=> 2x=97/4 – 7/2=83/4`
`=> x=83/4 : 2= 83/8`
