Question

Find the value of x satisfying the following equation x+2(x-1)=5/2​

Answer 1

Solution :

x + 2(x-1) = 5/2

>> x + 2x - 2 = 5/2

>> 3x - 2 = 5/2

>> 3x = 5/2 + 2

>> 3x = (5+4)/2

>> 3x = 9/2

>> x = 9/2 × ⅓

>> x = 3/2 = 1.5

Answer : The value of x satisfying the above equation is 1.5

Answer 2

$\sf\green{Given:-}$

• x + 2 ( x - 1 ) = 5/2

$\sf\green{Find:-}$

• Finding the value of x .

$\sf\green{Solution:-}$

$\tt\longmapsto{x + 2(x + 1) = \frac{5}{2} }$

$\tt\longmapsto{x + 2x - 1 = \frac{5}{2} }$

$\tt\longmapsto{3x - 2 = \frac{5}{2} }$

$\tt\longmapsto{3x = \frac{5}{2} + 2}$

$\tt\longmapsto{3x = \frac{5}{2} }$

$\tt\longmapsto{3x = 2.5 + 2}$

$\tt\longmapsto{3x = 4.5}$

$\tt\longmapsto{3x = 4.5 + 3}$

$\tt\longmapsto \fbox{x = 1.5}$

✴ So,

❝ So the answer is 1.5 [ option : b ] .❞
