8x + y = 9 <br> Convert the following equations to standard form
Citrus2011 [14]

Answer:

x=1/8y+9/8    

y=<u>y=−8x+9</u>

Step-by-step explanation:

<u>Let's solve for y.</u>

<u>8x+y=9</u>

<u>Step 1: Add -8x to both sides.</u>

<u>8x+y+−8x=9+−8x</u>

<u>y=−8x+9</u>

<u />

<u>Let's solve for x.</u>

<u>8x+y=9</u>

<u>Step 1: Add -y to both sides.</u>

<u>8x+y+−y=9+−y</u>

<u>8x=−y+9</u>

<u>Step 2: Divide both sides by 8.</u>

<u>8x/8=−y+9/8</u>

<u>x=−1/8y+9/8</u>
