\(x\times9,25+75\times x\)

\(\Rightarrow x\times\left(9,25+75\right)\)

\(\Rightarrow x\times84,25\)

Phần này sao sao ấy bạn???>>>mik giải tới đây......

\(x\times9,25+75\times x=???\)

\(x\times\left(9,25+75\right)=???\)

\(x\times84,25=???\)

BÀI này kêu đi tìm x mà sao thấy thiếu thiếu-------> XEM LẠI ĐỀ NHÉ

x X 9,25 +75%X x = 55,35

x.9,25+75%.x=55,35

b) \(x\cdot9,25+75\%\cdot x=55,35\)

\(\Leftrightarrow x\cdot9,25+0,75\cdot x=55,35\)

\(\Leftrightarrow x\left(9,25+0,75\right)=55,35\)

\(\Leftrightarrow10x=55,35\)

\(\Leftrightarrow x=5,535\)
