Answer:
We need to find a relationship between the equations.
Let's solve for one variable.
2x + 2y = 15
2y = 15 - 2x
We know what 2y is in relation to x. Now we can solve.
2x + 15-2x = 15
15 = 15
Unless there are more equations, this is your answer. For it to be simultaneous you need more than one equation.
