y = 2x + 2
or x + y = 6 That cannot be simplified further and to solve for either variable will require another independent eqaution in x and y
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.

Extraneous solution
sort of trajectory, solutions of eqaution of motion of a mechanical system,
The word eqaution for salt is:sodium cloride. sodium + chlorine= sodium chloride
y = 2x + 2
subsitution
This is potassium chloride (KCl).
No, there is no substitute.

Solution: 19 and 12. 19 + 12 = 31 19 - 12 = 7 Solve using subsitution or simultaneous equations.

Assuming that "eqaution" is your attempt to spell equation, y + 9 = -11 subtracting 9 from both sides: y = -20
