\(2x+25\%x=-2,25\)
\(\Leftrightarrow2x+\frac{25}{100}x=-\frac{225}{100}\)
\(\Leftrightarrow2x+\frac{1}{4}x=-\frac{9}{4}\)
\(\Leftrightarrow x\left(2+\frac{1}{4}\right)=-\frac{9}{4}\)
\(\Leftrightarrow\frac{9}{4}x=-\frac{9}{4}\)
\(\Leftrightarrow x=-\frac{9}{4}\div\frac{9}{4}\)
\(\Leftrightarrow x=-1\)
\(2x+25\%x=-2,25\)
\(2x+0,25x=-2,25\)
\(x.\left(2+0,25\right)=-2,25\)
\(x.2,25=-2,25\)
\(x=-2,25:2,25\)
\(x=-1\)
