Question

thaolanphuobg · Answer

3/4 - (x - 1/2) = 1 2/4   3/4 - (x - 1/2) = 3/2   x - 1/2 = 3/4 - 3/2   x - 1/2 = -3/4   x = (-3/4) + 1/2   x = -1/4

hatuanlan · Answer

3/4-(x-1/2)=1 2/4=(1xx4+2)/4=6/4     =>x-1/2=3/4-6/4=(-3)/4     =>x=(-3)/4+1/2=(-3)/4+2/4=(-1)/4

Tìm x: 3/4 – (x – 1/2)= 1và2/4
