Question

1+x/1-x=5/-4


solve for x​

Answer 1

Answer:

x=1/9

Step-by-step explanation:

By cross multiplication

5 (1-x)=4 (1+x)

5-5x=4+4x

5-4=4x+5x

1=9x

Therefore,

x=1/9

Answer 2

To find : value of $x$

Given : $\frac{1 + x}{1-x } = \frac{5}{-4}$

Solution :

• According to question we are given that $\frac{1 + x}{1-x } = \frac{5}{-4}$  . We have to find the value of $x$ from this given expression.

• To find the value of $x$  we cross multiply the given terms . $(-4) ( 1 + x ) = 5 ( 1 - x )$

             $-4 -4x = 5 -5x$

• Taking terms with variables at LHS and constants at RHS.
• $-4x + 5x = 5 -4$

                     $x = 1$  

Hence , value of $x$ is 1.
