Question

(2x+3/4):1/2=-5

Answer 1

(2x+3/4)/1/2=-5

2x+3/4=-5*1/2=-5/2

2x=(-5/2)-3/4=-13/4

x=(-13/4)/2=-13/8

Answer 2

x=-1,625Duyệt đi !

Answer 3

x=\(-\frac{13}{8}\)

Answer 4

(2x+\(\frac{3}{4}\)):\(\frac{1}{2}\)=-5

=>(2x+\(\frac{3}{4}\))=-5.\(\frac{1}{2}\)

=>2x=\(\frac{-5}{2}-\frac{3}{4}\)

=>2x=\(\frac{-13}{4}\)

=>x=\(\frac{-13}{4}:2\)

=>x=\(\frac{-13}{8}\)

Answer 5

x=-1,625

duyệt nhé BQT

Answer 6

(2x + 3/4) / 1/2 = -5

2x + 3/4 = -5 * 1/2 = -5/2

2x = (-5/2) - 3/4 = -13/4

x = (-13/4) / 2 = -13/8
