Ok, so \[2x4=4y?\]

Wait.. actually multiply the second equation by 4. That way you eliminate the x term

How would I subtract it from the first equation? X becomes eliminated than what?

When x is eliminated, you can find the y term

substitution method. (not elimination method) 4x + 2y = 11 x – 2 = – 2y (find 'x' from here, by adding 2 on both sides)

Once you find the y term, you can substitute it in any of the above equations, and then you get x.

@hartnn you'll still have the y term

x – 2 = – 2y x = 22y plug this in 1st equation 4(22y) +2y =11 simplify and get y

ask if you don't get that ^

@hartnn , but can't you solve it using elimination as well?

hartnnBest ResponseYou've already chosen the best response.1
the system can be solved by elimination method, but since the question specifically asks for substitution, we need to use substitution
