\( 210470,2 : 7,004 = 30042,857 \)
\( 47,4302 : 0,001 = 47430,2 \)
\( \frac{8,127}{(4,5x + 2,11)} = 70,6 \)
\( 8,127 = 70,6 \cdot (4,5x + 2,11) \)
\( \frac{8,127}{70,6} = 4,5x + 2,11 \)
\( 0,1151133144... = 4,5x + 2,11 \)
\( 0,1151133144 - 2,11 = 4,5x \)
\( -1,9948866856 = 4,5x \)
\( x = \frac{-1,9948866856}{4,5} \)
\( x \approx -0,4433 \)
\( 0,83x + 0,025x - 0,0042 = 0,03 \)
\( (0,83 + 0,025)x = 0,03 + 0,0042 \)
\( 0,855x = 0,0342 \)
\( x = \frac{0,0342}{0,855} \)
\( x = 0,04 \)
