Do you want to solve for x? The equation is already a function of x (ie y is dependent on x). If you do, then...




y=-7x-9 Start with the given equation



0=-7x-9-ySubtract y from both sides


%2B7x=-9-y Add 7x to both sides


x=%28-9-y%29%2F%287%29 Divide both sides by 7 to isolate x


--------------------------------------------------------------
Answer:
So our answer is x=%28-9-y%29%2F%287%29
