tim x biet 1/2(x-2/3)-1/3(2x-3)=x+1/2
Tim x biet : 20 . 2^x + 1 = 10.4^2 + 1
Tim x : ( 4-x:2)^3 - 1 = 2 . (2^3 - 5 : 2^0 )
Tim x biet
1/2.x+3/5.(x-2)=3
tim x biet (x-1)^4 :3^2=3^6
tim x thuoc N biet
x+(x+1)+(x+2)+(x+3)+.......+(x+30)=1240
1+2+3+.....+x=210
tim X biet
3^99 : (2.x-1)^3 = 3^97
tim x biet: (x+1)+(x-3)=x-2
tim x thuoc N biet 3x+2+3x+1+3x<1053
TIM X BIET: 3^99 : (2.X-1)=3^97
