Question

solve and check results x=3/6 (x + 9) plz answer me fast​

Answer 1

$\sf\large\red{\underline{Solution}}$

$\sf\tt\bf{x = \frac{3}{6}(x + 9)}$

$\sf\to \: \: x = \frac{1}{2}(x + 9)$

$\sf\to \: \: {x=\frac{1}{2}x+\frac{1}{2} \times9}$

$\sf\to\:\:{x = \frac{1}{2}x+\frac{9}{2}}$

$\sf\to\:\:{x - \frac{1}{2} x = \frac{9}{2} }$

$\sf\to\:\:{ \frac{1}{2}x = \frac{9}{2}}$

$\sf\to\:\:{x = \frac{9}{2}\times2}$

$\sf\:\:\purple{\to \: \: {x = 9}}$

$\sf\large\red{\underline{Verification}}$

• Substituting x = 9 on the LHS, we get

$\sf{ = 9}$

• Substituting x = 9 on the RHS, we get

$\sf \: \: \: \: {\frac{3}{6}(9 + 9)}$

$\sf{=\frac{3}{\cancel6_1}\times \cancel{18 \: _3}}$

$\sf{=3\times3}$

$\sf{ = 9}$

9 = 9

LHS = RHS

Hence, verified!!
