Step 1 :To determine if \((1,2)\) is a solution to the system of equations, we need to substitute \(x=1\) and \(y=2\) into both equations and check if both equations are satisfied.
Step 2 :Substitute \(x=1\) and \(y=2\) into the first equation, we get \(-2(1)-3(2) = -8\).
Step 3 :Substitute \(x=1\) and \(y=2\) into the second equation, we get \(3(1)-5(2) = -7\).
Step 4 :The result of substituting \(x=1\) and \(y=2\) into both equations does not satisfy the equations.
Step 5 :\(\boxed{\text{No, (1,2) is not a solution of the system.}}\)
