8.4x=4.25+150.36

8.4x=154.61

x= $18frac{3.41}{8.4}$

Ответ: x= $18frac{3.41}{8.4}$

Answer 2

$displaystyle tt 8,4(x-17,9)=4,25\displaystyle tt 8,4x-150,36=4,25\displaystyle tt 8,4x=4,25+150,36\displaystyle tt 8,4x=154,61\displaystyle tt x=154,61div8,4\\ displaystyle tt x=frac{15461}{840}\\ displaystyle tt bold{x=18frac{15461}{840}}$
