Is \[2y=11-4x\] Right?
Multiply the second equation by 2
and then subtract it from the first
Ok, so \[2x-4=-4y?\]
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 = 2-2y plug this in 1st equation 4(2-2y) +2y =11 simplify and get y
ask if you don't get that ^
@hartnn , but can't you solve it using elimination as well?
the system can be solved by elimination method, but since the question specifically asks for substitution, we need to use substitution
-8y +2y = ... ?
8-6y=11 -6y=3 y=-1/2
now find x

yes, it is correct.
Thanks! Should I give the medal to potatoes or you? He tried... but you helped
i'm not here for medals. you understand thats my medal :)
Also.. I'm a she :) And my method was wrong for this problem! Sorry!
