So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.
-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
I hope this helps love! :)
Answer:
you will most likely get red???
Step-by-step explanation:
Y=3 because it is horizantal line that is between 0 and 6
Answer:
1 Factor out the common term 22.
2(2x+y)=102(2x+y)=10
2 Divide both sides by 22.
2x+y=\frac{10}{2}2x+y=

to 55.
2x+y=52x+y=5
4 Subtract yy from both sides.
2x=5-y2x=5−y
5 Divide both sides by 22.
x=\frac{5-y}{2}x=

Answer:
When c = 6 and d = 34, there is one solution. When c = 8 and d = 6, there is no solution. When c = 8 and d = 12, there are infinitely many solutions.
Step-by-step explanation:
6x + 34 = 8x +12
-6x -6x
34 = 2x +12
-12 -12
22 = 2x
11 = x
8x + 6 = 8x +12
-8x -8x
6 = 12
No solution
8x+12= 8x + 12
-8x-12 -8x - 12
0 = 0
Infinite solutions
