Question

2/3×x-0,125=15/8

Giúp mình vs 

 

Answer 1

\(\frac{2}{3}\cdot x-0,125=\frac{15}{8}\)

\(\frac{2}{3}\cdot x=\frac{15}{8}+0,125=\frac{15}{8}+\frac{1}{8}=2\)

\(x=2:\frac{2}{3}=2\cdot\frac{3}{2}=3\)

Vậy x=3

Answer 2

2/3.x - 0,125 = 15/8

    2/3.x - 1/8 = 15/8

            2/3.x = 15/8 +1/8

            2/3.x = 2  

                 x = 2:2/3

                 x = 3
