Question

75%*x+0,25*x+x:0,5=33,6

Answer 1

\(\Leftrightarrow\dfrac{3}{4}x+\dfrac{1}{4}x+x:\dfrac{1}{2}=33,6\\ \Leftrightarrow\dfrac{3}{4}x+\dfrac{1}{4}x+2x=33,6\\ \Leftrightarrow\left(\dfrac{3}{4}+\dfrac{1}{4}+2\right)x=33,6\\ \Leftrightarrow3x=33,6\\ \Leftrightarrow x=33,6:3\\ \Leftrightarrow x=11,2\)

Answer 2

`75`%\(\times x+0,25\times x+x:0,5=33,6\)

\(0,75\times x+0,25\times x+x\times2=33,6\)

\(x\times(0,75+0,25+2)=33,6\)

\(x=3=33,6\)

`x=33,6:3`

`x=11,2`
