Question

4.8 (3-X) - 2 (2.3x - 6.9) = 0 and verify your result.
​

Answer 1

$\bf \red{ \underline{ \underline{solution}}}$

$4.8(3 - x) - 2(2.3x - 6.9) = 0$

$= > 14.4 - 4.8x - 4.6x + 13.8 = 0$

$= > 28.2 - 9.4x = 0$

$= > 9.4x = 28.2$

$= > x = \frac{28.2}{9.4}$

$= > \orange{x = 3}$

$\bold {verfication}$

$L.H.S = 4.8(3x - x) - 2(2.3x - 6.9)$

$\blue{putting \: the \: value \: of \: x}$

$= > 4.8(3 - 3) - 2(2.3 \times 3 - 6.9)$

$= > 4.8 \times 0 - 2(6.9 - 6.9)$

$= > 0 - 2 \times 0$

$= > 0$

$L.H.S = RHS \: for \: = 3.$

$\pink{hence \: the \: solution \: is \: verified}$

Answer 2

$\huge\underline\mathcal\purple{Answer:}$

=> 4.8(3 − x) − 2(2.3x − 6.9) = 0

=> 14.4 - 4.8x - 4.6x + 13.8 = 0

=> 28.2 - 9.4x = 0

=> 9.4x = 28.2

=> x = $\dfrac{28.2}{9.4}$

=> x = 3

$\huge\underline\mathcal\purple{Verification:}$

Putting the value of x in the L. H. S

=> 4.8(3 − x) − 2(2.3x − 6.9)

=> 4.8(3 − 3) − 2(2.3 × 3 − 6.9)

=> 4.8 × 0 - 2(6.9 − 6.9)

=> 0 - 2 × 0

=> 0

R. H. S = 0

∴ L. H. S = R. H. S

Hence verified !!
