Solve the equations for the solutions, x and y.
x - y = 0
6x + 5y = -22 Found 2 solutions by Maths68, josmiceli:Answer by Maths68(1474) (Show Source):
You can put this solution on YOUR website! x-y=0........(1)
6x+5y=-22....(2)
Take (1)
x-y=0
x=y.......(3)
Put the value of x in (2)
6x+5y=-22....(2)
6y+5y=-22
11y=-22
11y/11=-22/11
y=-2
Put the value of x in (3)
x=y
x=-2
x,y=-2,-2
Check
======
Put the value of x and y in (1)
x-y=0
-2-(-2)=0
-2+2=0
0=0
Put the value of x and y in (2)
6x+5y=-22....(2)
6(-2)+5(-2)-22
-12-10=-22
-22=-22
You can put this solution on YOUR website! (1)
(2)
If it doesn't matter what method to use,
the easiest way is by substitution
-------------
Add to both sides of (1)
(1)
Now where I see in equation (2),
I can substitute
(2)
(2)
(2)
Now if I plug this value of
back into (1), I get
(1)
(1)
Subtract from both sides
(1)
So, the solution is (-2,-2)
Here's a plot of the equations that shows this:
