Answer 1

Answer:

-2/4=x

-2=x

answer x=-2

Answer 2

Given:

The equations-

$\bf -2 = \dfrac{4}{x}$

What To Find:

We have to find the value of x.

How To Find:

• Use cross multiplication.
• Solve the LHS.
• Solve the RHS.
• Find the value of x.

Solution:

$\sf -2 = \dfrac{4}{x}$

Use cross multiplication,

⇒ -2 × x = 4

Multiply the -2 and x,

⇒ -2x = 4

Take -2 to RHS,

⇒ x = - 4/2

Divide -4 by 2,

⇒ x = -2

∴ The value of x is -2.

Verification:

$\sf -2 = \dfrac{4}{x}$

Substitute the values,

⇒ -2 = -4/2

Solve the RHS,

⇒ -2 = -2

∴ LHS = RHS. Hence, verified.
