Question

[Đoàn Trần]

tim x                       x +3/4 bang 1/2 +9/8

Answer 1

[⭐Hannie⭐]

\(x+\dfrac{3}{4}=\dfrac{1}{2}+\dfrac{9}{8}\\ x+\dfrac{3}{4}=\dfrac{4}{8}+\dfrac{9}{8}\\ x+\dfrac{3}{4}=\dfrac{13}{8}\\ x=\dfrac{13}{8}-\dfrac{3}{4}\\ x=\dfrac{13}{8}-\dfrac{6}{8}\\ x=\dfrac{7}{8}\)

Answer 2

[Nguyễn Quang Minh]

x + 3/4 = 1/2 + 9/8

x + 3/4 = 13/8

      x    = 13/8 -3/4

      x    = 7/8
