Question

tìm x

A) (\(\chi\)x 0,25 + 1999) x 2000= (53+ 1999) x 2000

b) 71 + 65 x 4=\(\frac{\chi+140}{\chi}\)+ 260.

Ai biết làm thì giúp mik nhé

Answer 1

a)(x.0,25+1999)x2000=(53+1999)x2000

(x.0,25+1999)=53+1999

x.0,25=53

x=53x4

x=210

Answer 2

a)(x.0,25+1999)x2000=(53+1999)x2000

(x.0,25+1999)=53+1999

x.0,25=53

x=53x4

x=210

k mik đi

Answer 3

(x .0,25 + 1999) . 2000 = (53+1999) .2000

(x . 0,25 +1999 )= (53 +1999)

x. 0,25= 53

x         = 53 :0, 25

x         = 212
