tim x
a, ( x 0,25+1999).2000=(53+1999).2000
b, 71+65.4=x+140/x+260
Tìm x :
a) \(\times.\left(0,25+1999\right).2000=\left(53.1999\right).2000\)
b) 71 + 65 x 4 = \(\frac{x+140}{x}+260\)
Bài 1:tìm x:
a) x+5*2-(32+16*3*6-15)= 0
b) (x*0,25+1999)*2000= (53+1999)*2000
c)x*2016=x:2016
d) (x+2)+(x+3)+.....................+ (x+100)= 5750-(x-1)
e) x+x:1/3:2/9+x:2/7= 252
g) 71+65*4=\(\frac{x+140}{x}\) + 260
