Question

Tìm x :

x : 0,25 + x nhân 6 = 12,6 

Ai nhanh mình tick cho nha

Answer 1

x : 0,25 + x × 6 = 12,6

x × 4 + x × 6 = 12,6

x × (4 + 6) = 12,6

x × 10 = 12,6

x = 12,6 : 10

x = 1,26

Answer 2

\(x:0,25+x\times6=12,6\)

\(=>x\times4+x\times6=12,6\)

\(=>x\times\left(4+6\right)=12,6\)

\(=>x\times10=12,6\)

\(=>x=12,6:10\)

\(=>x=1,26\)

Vậy...
