Question

$\frac{3(d - 2)}{9} + 5 = 7$
give the answer step by step ​

Answer 1

$\Large {\underline{\underline{\textbf{\textsf{\pink{Solution:}}}}}}$

• $\sf \dfrac{3(d - 2)}{9} + 5 = 7$

$\sf :\implies \dfrac{\cancel{3}(d - 2)}{\cancel{9}} + 5 = 7$

$\sf :\implies \dfrac{d - 2}{3} + 5 = 7$

$\sf :\implies \dfrac{d - 2}{3} = 7 - 5$

$\sf :\implies \dfrac{d - 2}{3} = 2$

$\sf :\implies d - 2 = 2\times 3$

$\sf :\implies d - 2 = 6$

$\sf :\implies d = 6+2$

$\sf :\implies d = 8$

$\: \: \: \: \: \: \: \: \: \large \maltese \: \: \underline{\boxed{\pink{\bf d = 8}}}\: \: \maltese$

Hence, value of d is $\pink{\bf 8}$.
