-6x+9-4x=14 The value for x

$- 6x + 9 - 4x = 14$

$- 6x - 4x + 9 = 14$

Collect like terms

$( - 6 - 4)x + 9 = 14$

$- 10x + 9 = 14$

Subtract sides 9

$- 10x + 9 - 9 = 14 - 9$

$- 10x = 14 - 4 - 5$

$- 10x = 10 - 5$

$- 10x = 5$

Divide sides by - 10

$\frac{ - 10x}{ - 10} = \frac{5}{ - 10} \\$

$x = - \frac{5}{10} \\$

$x = - \frac{5}{5 \times 2} \\$

$x = - \frac{1}{2} \\$
