Question

7x+4)/(x+2) = -4/5, find the value of x:

Answer 1

Answer:

$\dfrac{-28}{39}$

Step-by-step explanation:

Given:

$\frac{7x+4}{x+2} =\frac{-4}{5}$

To find:

• Value of X by solving the above equation

$\frac{7x+4}{x+2} =\frac{-4}{5}$

Cross multiplying the equation:

(7x+4)(5)=(x+2)(-4)

35x+20= -4x-8

35x+4x+20 = -8

39x+20 = -8

39x = -8-20

39x = -28

x = $\dfrac{-28}{39}$

The value of X is equal to $\dfrac{-28}{39}$

The value of variables in linear equations in two variables can be solved by:

• Substitution method
• Elimination method
• Cross multiplication method
