Question

What is the excluded value?

Answer 1

Answer:

Excluded value = -7

Solution = $x = \frac{5}{9}$

Step-by-step Explanation:

The excluded value is the value that will make the denominator 0.

Thus,

$x + 7 = 0$

Subtract 7 from both sides

$x + 7- 7 = 0 - 7$

$x = -7$

The excluded value is -7

Solution=>

$\frac{2x}{x + 7} + \frac{3x + 1}{x + 7} = \frac{1}{2}$

$\frac{2x + (3x + 1)}{x + 7} = \frac{1}{2}$

$\frac{5x + 1}{x + 7} = \frac{1}{2}$

Cross multiply

$2(5x + 1) = 1(x + 7)$

$10x + 2 = x + 7$

$10x - x = -2 + 7$

$9x = 5$

$x = \frac{5}{9}$
