Does either of the equations have an isolated variable in it?
(-11,-19)
When solving a system of equations using substitution, there are three steps.
(I): LHS+2x=RHS+2x
(II):y= 2x+3
(II):Distribute - 2
(II):Subtract terms
(II):LHS+6=RHS+6
(II): LHS * (-1)=RHS* (-1)
(I):x= - 11
(I): a(- b)=- a * b
(I):Add terms
(I), (II): x= -11, y= -19
(I), (II): Multiply
(I), (II): Add terms
