How do you solve the system of equations 4 x − 2 y = 1 and -4 + 4 y = -2

Mathematics

Dmitrij [34]3 years ago

Answer: y= -2 - 1/2

Step-by-step explanation:

-4x -2y = 1

+4x       +4x

-2y = 4x + 1

/-2    /-2    /-2

y= -2 - 1/2

I think, i may be incorrect but the verbal explanation is; -4x is needed to be moved so you add 4x to both sides and 4x cancels out on the left which leaves -2y on the left (when it was moved "x" is always first). then divide all numbers by -2 to get y by itself. this gives you y= -2 - 1/2 if my calculations are correct.

Is anyone good at geometry???
zhenek [66]
Hey there Smarty!

This would be considered to be a (acute angel) which in this case, we would have to make sure that this whole triangle would equal less than 270 because each angle would be less than 90°

If we add/multiply \boxed{(90+90+90) \ or \ (90*3) = 270}.

So, we would have to know that was ever this would all add up to be, this would have to be less than 270°

\left[\begin{array}{ccc}\boxed{\boxed{(2.5+5) \\ \\ (2.5*2.5) \\ (2.5-2) \\ (2.5-1) \\}} \\ \\ this \ would \ be \ why \ I \ would \ say \\ that \ this \ would \ be \ the \ answer \end{array}\right]

I truly hope this helps, and also, it's kind of my 
 first time doing this I hope this would be helpful.
