Question

The sum of three rational numbers 2/9, , -1/18 and x is 1/2. Find the value of x.​​

Answer 1

Step-by-step explanation:

$\\ \sf{:}\dashrightarrow \dfrac{2}{9}+\dfrac{-1}{18}+x=\dfrac{1}{2}$

$\\ \sf{:}\dashrightarrow \dfrac{4+(-1)}{18}+x=\dfrac{1}{2}$

$\\ \sf{:}\dashrightarrow \dfrac{4-1}{18}+x=\dfrac{1}{2}$

$\\ \sf{:}\dashrightarrow \dfrac{3}{18}+x=\dfrac{1}{2}$

$\\ \sf{:}\dashrightarrow x=\dfrac{1}{2}-\dfrac{3}{18}$

$\\ \sf{:}\dashrightarrow x=\dfrac{9+3}{18}$

$\\ \sf{:}\dashrightarrow x=\dfrac{12}{18}$

$\\ \sf{:}\dashrightarrow x=\dfrac{2}{3}$
