Question

3x-2 / 7. -2 = x-2 / 4 . Find the value of x​

Answer 1

32*74

=10

Expanding the determinant, we get

⇒12x−14=10

⇒12x=10+14

⇒12x=24

⇒x=2

=10

Expanding the determinant, we get

⇒12x−14=10

⇒12x=10+14

⇒12x=24

⇒x=2

Answer 2

Given :

• $\sf\:\frac{3x-2}{7}-2=\frac{x-2}{4}$

‎

To find :

• The value of x

‎

Solution :

$\sf\:\frac{3x-2}{7}-2=\frac{x-2}{4}$

$\sf\rightarrow\:\frac{3x-2-14}{7}=\frac{x-2}{4}$

$\sf\rightarrow\:\frac{3x-16}{7}=\frac{x-2}{4}$

Cross multiplying

$\sf\rightarrow\:4(3x-16)=7(x-2)$

$\sf\rightarrow\:12x-64=7x-14$

$\sf\rightarrow\:12x-7x=64-14$

$\sf\rightarrow\:5x=50$

$\sf\rightarrow\:x=\cancel{\frac{50}{5}}$

$\small{\underline{\boxed{\mathrm{\rightarrow\:x=10}}}}$
