Question

3) 9 – 5(x – 1) + x = 4x – 18

Answer 1

9 – 5(x – 1) + x = 4x – 18

9-5x+5+×=4x-18

14-4x= 4x-18

14-18= 8x

-4=8x

×= -1/2

Answer 2

Respuesta:

$x=4$

Explicación paso a paso:

$9-5\left(x-1\right)+x=4x-18\\-4x+14=4x-18\\-4x+14-14=4x-18-14\\-4x=4x-32\\-4x-4x=4x-32-4x\\-8x=-32\\\frac{-8x}{-8}=\frac{-32}{-8}\\x=4$
