Plzzz helppp!!<br> 9-4x=17????
AnnyKZ [126]

Answer:

<h3>\boxed{ \bold{ \boxed{ \sf{x =  - 2}}}}</h3>

Step-by-step explanation:

\sf{9 - 4x = 17}

Move 9 to right hand side and change it's sign

⇒\sf{ - 4x = 17 - 9}

Subtract 9 from 17

⇒\sf{ - 4x = 8}

Divide both sides of the equation by -4

⇒\sf{ \frac{ - 4x}{ - 4}  =  \frac{8}{ - 4}}

Calculate

⇒\sf{x =  - 2}

Hope I helped!

Best regards!!
