Solve for \( r \):
\[ 6qr + 7rs - 2st = -9 \]
Answer (2)
In this particular instance, r can be solved as far as to establish it is equal to -9 + 2st over 6q + 7s. You cannot solve the equation further than this, but the part from this is as follows: 6qr + 7rs - 2st = -9 6qr + 7rs = -9 + 2st r(6q+7s) = -9 + 2st if you simplify this down further, you will find the answer mentioned above.
To solve for r , we rearrange the given equation to isolate r on one side. This leads to the equation r = 6 q + 7 s − 9 + 2 s t . The solution shows r expressed in terms of other variables, and cannot be simplified further without knowing their values.
