Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
3w-13w=-20
Combine like terms
-10w=-20
divide both sides by -10
w=2
I know m=2.25 and n=8.6 but I don't know about q.
There is no picture with this so I don’t know how to answer this
