Question

Whats x+7y=-39?

Please help me and show me how to work this whole thing out thank you so much!!!

Answer 1

Explanation:

Let's solve for x.

x+7y=−39

Step 1: Add -7y to both sides.

x+7y+−7y=−39+−7y

x=−7y−39

Let's solve for y.

x+7y=−39

Step 1: Add -x to both sides.

x+7y+−x=−39+−x

7y=−x−39

Step 2: Divide both sides by 7.

7y/7 = −x−39/7

y= −1/7x+−39/7
