đún thì cho mk nhé

chúc bạn học tốt

8,75 x X + 1,25 x X = 2

X x ( 8,75 + 1,25 ) = 2

X x 10 = 2

X = 2 : 10

X = 0,2

\(8,75.x+1,25.x=2\)

\(< =>x\left(8,75+1,25\right)=2\)

\(< =>x.10=2\)

\(< =>x=2:10=\frac{2}{10}=\frac{1}{5}\)

\(8,75\times x+1,25\times x=2\)
\(\left(8,75+1,25\right)\times x=2\)
\(10\times x=2\)
\(x=2:10\)
\(x=0,2\)

8,75 * x + 1,25 * x = 20

8,75 * x + 1,25 * x = 20

x                          = 20 : ( 8,75 + 1,25 )

x                          = 20 : 10

x                          = 2

( 8,75 + 1,25 ) x X = 20 

10 x X = 20

       X = 20 : 10

      X = 2

cám mơn nhé 

8,75 x X + 1,25 x X = 20

= ( 8,75 + 1,25 ) x X = 20

=         10            x X = 20

X = 20 : 10 

X = 2
