Step-by-step explanation:

$\frac{3}{2x + 5} + \frac{5}{x - 5} \\ \\ = \frac{3(x - 5) + 5(2x + 5)}{(2x + 5)(x - 5)} \\ \\ = \frac{3x - 15 + 10x + 25}{(2x + 5)(x - 5)} \\ \\ = \frac{3x + 10x + 25- 15 }{2 {x}^{2} - 10x + 5x - 25 } \\ \\ = \frac{13x + 10 }{2 {x}^{2} - 5x - 25 } \\ \\$

Solve the two-step equation.<br><br> 14 = 31.7 – 3x<br><br> What is the solution?

shtirl [24]

Answer:

The answer is 5.9

Step-by-step explanation:

1) Subtract 31.7 from both sides.

$14 - 31.7 = - 3x$

2) Simplify 14 - 31.7 to -17.7

$- 17.7 = - 3x$

3) Divide both sides by -3.

$\frac{ - 17.7}{ - 3} = x$

4) Simplify -17.7/-3 to 5.9

$5.9 = x$

5) Switch sides.

$x = 5.9$

Therefor, the answer is x = 5.9.
