( x/-5+2/3):11/5-1,4*15/49= I-5I/21

ai giải giúp mk với  mk cần gấp lắm. ai nhanh mk tick cho ( nhớ lm cụ thể)

Answer 1

(x/-5+2/3);11/5-1,4.15/49=|-5|/21

(x/-5+2/3);11/5-1,4.15/49=5/21

(x/-5+2/3);11/5-21/49=5/21

(x/-5+2/3);11/5=5/21+21/49

(x/-5+2/3);11/5=35/147+63/147

(x/-5+2/3);11/5=35+63/147

(x/-5+2/3);11/5=98/147

x/-5+2/3=98/147.11/5

x/-5+2/3=98.11/147.5

x/-5+2/3=1078/735

x/-5+2/3=154/105

x/-5=154/105-2/3

x/-5=154/105-70/105

x/-5=154-70/105

x/-5=84/105

x/-5=-4/-5

suy ra x=-4
