Answer 2

Answer:

x = 15

Step-by-step explanation:

Given : ${\sf{\ \ {\dfrac{x}{3}} + 7 = {\dfrac{2x}{3}} + 2}}$

On further solving, we get

$\Rightarrow{\sf{ {\dfrac{x + 7(3)}{3}} = {\dfrac{2x + 2(3)}{3}}}}$

$\Rightarrow{\sf{ {\dfrac{x + 7(3)}{{\cancel{3}}}} = {\dfrac{2x + 2(3)}{{\cancel{3}}}}}}$

$\Rightarrow$ x + 7(3) = 2x + 2(3)

$\Rightarrow$ x + 21 = 2x + 6

Transposing the terms.

$\Rightarrow$ 2x - x = 21 - 6

$\Rightarrow$ x = 15

Verification :

L.H.S. = ${\sf{{\dfrac{x}{3}} + 7}}$

$\Rightarrow{\sf{ {\dfrac{15}{3}} + 7}}$

$\Rightarrow$ 5 + 7

$\Rightarrow$ 12

R.H.S. = ${\sf{{\dfrac{2x}{3}} + 2}}$

$\Rightarrow{\sf{ {\dfrac{2(15)}{3}} + 2}}$

$\Rightarrow{\sf{{\dfrac{30}{3}} + 2}}$

$\Rightarrow$ 10 + 2

$\Rightarrow$ 12
