Question

Solve the simultaneous equations 2x+2y=15

Answer 1

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.
