Question

1 . Tìm \(x\)

\(^{\left(74,25+\frac{3}{4}\right)\times x-131,5=18,5}\)

Answer 1

\(\left(74,25+\frac{3}{4}\right)\times x-131,5=18,5\)

\(75\times x=18,5+131,5\)

\(75\times x=150\)

\(x=150:75\)

\(x=2\)

Answer 2

\(\frac{3}{4}=0,75\)

(74,25+0,75)x\(x\)-131,5=18,5

75 x \(x\)-131,5=18,5

75x\(x\)     =18,5+131,5

75x\(x\)     =150

\(x\)     =150:75

\(x\)      =2

Answer 3

\(\left(74,25+\frac{3}{4}\right).x-131,5=18,5\)

\(75.x=18,5+131,5\)

\(75.x=150\)

\(x=150:75\)

\(x=2\)
