Did you copy the equations correctly? The third one is not consistent with the others. If we ignore the third equation, then x = 2 and y = 4.
Take equation #1 and multiply it by â8. Then take the result and add it to equation #4. The y's cancel out and you have 4x = 8. This gives you the value of x. From this you can get y. Or you can use equation #2, where the x is multiplied by zero and may be omitted, and you get the value of y.
But if equation #3 is included as is, then none of that works because eq #3 says that x = 20.

X and Y is irrelavant.
The answers are all wrong.
Just like 1 blob of ice cream + a block of cheese does not = a lump of wood.

It is impossible to answer this question! The system of equations is inconsistent!
