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
<span>x − 9y ≤ 1
</span>Because If you solve the equation y will be greater than ...
<span>x − 9y ≤ 1
Solve for y...
Subtract x from both sides...
- 9y </span>≤<span> - x + 1
Divide both sides by -9
REMEMBER WHEN DIVIDING OR MULTIPLYING BY A NEGATIVE NUMBER FLIP THE INEQUALITY SIGN....
y </span><span> ≥ x/9 - 1/9</span>
