Question

0.5x-(0.8-0.2x)=0.2-0.3 solve eauation

Answer 1

${\large{\mathfrak{\underline{\underline{Solution :}}}}}$

$\sf{0.5x - (0.8 - 0.2x) \ = \ 0.2 - 0.3}$

$\sf{\implies 0.5x - 0.8 + 0.2x \ = \ 0.2 - 0.3}$

$\sf{\implies 0.7x - 0.8 \ = \ - 0.1}$

$\sf{\implies 0.7x \ = \ - 0.1 + 0.8}$

$\sf{\implies 0.7x \ = \ 0.7}$

$\sf{\implies x \ = \ {\dfrac{0.7}{0.7}}}$

$\sf{\implies x \ = \ 1}$

Answer 2

$0.5 x - (0.8 - 0.2x) = 0.2 - 0.3...........(1) \\ \\ multiplying \: equation(1) \: by \: 10 \\ \\ 5x - (8 - 2x) = 2 - 3 \\ \\ = > 5x - 8 + 2x = - 1 \\ \\ = > 5x + 2x = - 1 + 8 \\ \\ = > 7x = 7 \\ \\ = > x = \frac{7}{7} \\ \\ = > x = 1$


hope it helps.....
