how would i solve this ? 6 − x = 15

Question

zzr0ck3r · Answer

start by subtracting 6 from woth sides and see what you get

anonymous · Answer

what you need to do is isolate x, so that it is positive and by itself

this can be done by subtracting 6 from both sides of the equation
$$6-x-6=15-6$$
$$-x=9$$
because x needs to be positive, this can be done by multiplying it by (-1)
however, whenever you do anything to one side of the equation, the same must be done for the other side

$$(-1)*(-x)=(-1)*(9)$$
$$x=-9$$

for any future problems, always remember that if you ever add, subtract, multiply, divide. you must always do it to both sides

6-6 is0 and 15-6=9

so would it be x=9-15 or some thing ?
