Question

0.3(6-x)= 0.4(x+8)
$0.3(6-x)= 0.4(x+8)$
​

Answer 1

$0.3(6 - x) = 0.4(x + 8)$

$\rightarrow1.8 - 0.3x = 0.4x + 3.2$

$\rightarrow - 0.3x - 0.4x = 3.2 - 1.8$

$\rightarrow - 0.7x = 1.4$

$\rightarrow \: x = - \frac{1.4}{ 0.7}$

$\fbox\blue { x \: = - 2}$

${\sf\bold{Verification~:}}$

$0.3(6 - ( - 2)) = 0.4( - 2 + 8)$

$0.3 \times 8 = 0.4 \times 6$

$2.4 = 2.4$
