Can anybody show me the steps to answering this question? 7x - 2z = 4 - xy

(solve for x)

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy = xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x (y+7) = 2z+4

You divide both sides by y+7

x (y+7) / y+7 = 2z+4/y+7

Which we would get x=2z+4/y+7
